Africa Is Growing Thanks to the Free Market

Since the new millennium's start, Africa's average per capita income rose by more than 50 percent.

Sub-Saharan Africa consists of 46 countries and covers an area of 9.4 million square miles. One out of seven people on earth live in Africa and the continent’s share of the world’s population is bound to increase, because Africa’s fertility rate remains higher than elsewhere. If current trends continue, there will be more people in Nigeria than in the United States by 2050. What happens in Africa, therefore, is important not only to the people who live on the continent, but also to the rest of us.

Africa may be the world’s poorest continent, but it is no longer a “hopeless continent,” as The Economist magazine described it back in 2000. Since the start of the new millennium, Africa’s average per capita income adjusted for inflation and purchasing power parity rose by more than 50 percent and Africa’s growth rate has averaged almost 5 percent per year.

Increasing wealth has led to improvements in key indicators of human wellbeing. In 1999, 58 percent of Africans lived on less than $1.90 per person per day. By 2011, 44 percent of Africans lived on that income – all while the African population rose from 650 million to 1 billion. If the current trends continue, Africa’s absolute poverty rate will fall to 24 percent by 2030.

Life expectancy rose from 54 years in 2000 to 62 years in 2015. Infant mortality declined from 80 deaths per 1,000 live births to 49 deaths over the same time period. When it comes to HIV/AIDS, malaria and tuberculosis, occurrence, detection, treatment and survival rates have all improved. Food supply exceeds 2,500 calories per person per day (U.S. Department of Agriculture recommends consumption of 2,000 calories) and famines have disappeared outside of warzones. Primary, secondary and tertiary school enrollments have never been higher.

Some of Africa’s growth was driven by high commodity prices, but much of it, a McKinsey study found in 2010, was driven by economic reforms. To appreciate the latter, it is important to recall that for much of their post-colonial history, African governments have imposed central control over their economies. Inflationary monetary policies, price, wage and exchange rate controls, marketing boards that kept the prices of agricultural products artificially low and impoverished African farmers, and state-owned enterprises and monopolies were commonplace.

That began to change after the fall of the Berlin Wall. Socialism lost much of its appeal and the Soviet Union, which bankrolled and protected many African dictatorships, fell apart. Between 1990 and 2013, economic freedom as measured by the Fraser Institute in Canada rose from 4.75 out of 10 to 6.23. Freedom to trade rose even more, from 4.03 to 6.39. Most impressively, Africa has made much progress in terms of monetary policy, or access to sound money, which rose from a low of 4.9 in 1995 to a remarkable 7.27 in 2013.

Africa has made similar strides in terms of microeconomic policy. As the World Bank’s Doing Business report indicates, Africa’s regulatory environment has much improved. Starting a business, for example, has become easier, with Africa’s score rising from 45 out of 100 in 2004 to 72 in 2015. Dealing with construction permits, resolution of insolvencies, enforcement of contracts, access to electricity, the ease of payment of taxes, registering of property and getting of credit, have all much improved.

Unfortunately, there has been no substantial improvement in the quality of Africa’s institutions. According to the Freedom House’s Freedom in the World 2016 report, there were only 6 free countries in sub-Saharan Africa: Benin, Botswana, Ghana, Namibia, Senegal and South Africa. While many countries have adopted more “democratic” constitutions that include term limits, and other legislative and institutional checks on the executive branch of government, African rulers have found a way around those provisions in order to maintain power and abuse it.

According to the World Bank, corruption continues to thrive among government officials and, importantly, among members of the judiciary. As a consequence, rule of law indicators for African countries have remained, by and large, unchanged. Yet without efficient and impartial courts, Africa’s economic potential will always remain unfulfilled.

That said, as experience in other regions shows, institutional development tends to lag behind economic reforms. In the medium to long run, growth of the African middle class might yet result in a political awakening and greater assertiveness of the African populace, and eventual democratization of the continent.

The new millennium has been good to Africa, but the continent is still far from being prosperous, let alone democratic. In order for Africa’s economy to go on expanding, Africans will need to continue with their reforms – never forgetting that the world economy keeps on changing and global competition keeps on increasing. That is Africa’s challenge as well as its opportunity.

The Rise of Contact Lens Abundance

Get almost 16 today for the time price of one in 1971.

Summary: Since the introduction of the first US commercial soft contact lenses, significant advancements have made them more accessible and affordable. This progress in abundance, driven by continuous innovation, underscores the importance of fostering an environment conducive to scientific and entrepreneurial advancements for the prosperity of society.


In 1971, Bausch & Lomb manufactured the first US commercial soft contact lenses. An eye doctor fitting ran around $550, and a pair of contact lenses cost $65, putting total costs around $615. Unskilled workers at the time earned about $2 an hour. This means the time price was about 307.5 hours.

Today an eye exam is about $120, and lenses start at $200 for a 12-month supply, putting the cost at $320. Unskilled workers now earn about $16.51 an hour, indicating a time price of 19.4 hours.

Unskilled workers can now get 15.9 sets of contact lenses for the time price of one set in 1971. Abundance has been growing at a compound annual rate of 5.35 percent, doubling in abundance every 13.3 years.

Today an estimated 45 million Americans wear contact lenses, of which 30 million are women. Imagine if the manufacturers of eyeglasses had used government regulation and coercion to prevent the innovation of contact lenses?

The more we make of something, the more we learn. The more we learn, the lower the price. The lower the price, the higher our standard of living. This truth was described by Adam Smith in 1776 in The Wealth of Nations.

And what is wealth? As George Gilder notes, “Wealth is knowledge and growth is learning.” The nation that is best at growing new knowledge will enjoy the greatest wealth. Artificial intelligence offers the hope that this learning process can be dramatically enhanced.

We can thank the continuous innovations of scientists and entrepreneurs in developing new contact lens designs and manufacturing techniques. America’s comparative advantage has been its visionary leadership in encouraging everyone in discovering and creating valuable new knowledge that can be shared in free markets. We cannot allow fear to blind us to these truths and prevent a future of innovation and greater prosperity.

The Good Old Days Were Really Expensive

Most things are more abundant and affordable today.

If you had a dime in 1900, you could buy a 1-ounce Hershey chocolate bar and a 6.5-ounce bottle of Coca-Cola. It sounds like those were happy days indeed. That is until you look at wages, which were around 14 cents an hour for blue-collar workers.

At Walmart today, a 1.55-ounce Hershey bar costs $1.17 and a 1.25-liter bottle (42.27 ounces) of Coke is $1.52. Blue-collar workers earn closer to $36.15 an hour in compensation.

We buy things with money but pay for them with our time. Money prices are expressed in dollars and cents, while time prices are expressed in hours and minutes. A time price is simply the money price divided by hourly income.

In 1900, it took more than 21.4 minutes to earn an ounce of chocolate and 3.3 minutes for an ounce of Coca-Cola. By 2023, the chocolate time price had fallen to 1.25 minutes, and sodas were down to 0.06 minutes (3.58 seconds).

Chocolate cost fell 94.2 percent while cola cost fell 98.2 percent. For the time required to earn 1 ounce of chocolate in 1900, you get 17.1 ounces today, and for the time required to earn 1 ounce of Coca-Cola in 1900, you get 55.2 ounces today. Chocolate is 1,611 percent more abundant while cola is 5,425 percent more abundant.

Things can get more expensive and more affordable at the same time. This is why you must always compare prices to wages to see the true price, which is how much time things cost you.

Where Is Gasoline the Most Affordable?

Remember that it’s the time price, not the money price, that counts.

Summary: The affordability of gasoline varies significantly worldwide due to varying taxes and subsidies. Analyzing the GDP per hour worked against the money price per gallon shows that the United States emerges as the most affordable country for purchasing gasoline, even compared to nations where gasoline prices are heavily subsidized by the government.


According to GlobalPetrolPrices.com, the average price of gasoline around the world is USD5.03 per gallon. However, there is substantial difference in these prices among countries due to the various taxes and subsidies for gasoline. All countries have access to the same petroleum prices of international markets, but countries do not all impose the same taxes. As a result, the retail price of gasoline varies significantly.

Graph displays the gasoline price per gallon in US dollars in various countries

The money price of 16 selected countries ranges from $2.26 in Russia to $8.55 in Denmark. But what about the time price? To calculate the time price, we first calculated the GDP per hour worked in each country. The data to calculate this ratio come from the World Bank and the Conference Board.

Graph displays the GDP per hour worked in various countries

We then divided GDP per hour worked by the money price per gallon. This gave us the gallons of gasoline that one hour of work would buy in each country:

We also divided the nominal price per gallon by GDP per hour worked to get the minutes required per gallon:

This chart illustrates how much more expensive relative to the US the other 15 countries are in terms of time price:

Chart displays the cost in time price of gasoline in 15 countries

Of the 16 countries analyzed, the US is by far the most affordable place to buy gasoline. There are other countries where gasoline is more affordable, but the gasoline price in those countries is heavily subsidized by government.

Flying Abundance (And Safety) Has Increased Dramatically

Get 10.8 flights from New York to London today for the time price of one in 1970 and be 80.4 times safer.

Summary: Since the Wright brothers’ pioneering flight in 1903, the aviation industry has made remarkable strides in safety, affordability, and accessibility. Comparing flight prices from 1970 to today reveals a staggering 90.8 percent decrease in the time price of flying, with transcontinental flights now affordable for the average person. Additionally, advancements in aviation technology have made flying dramatically safer today than it was in 1970, and are likely to improve flying safety in the future.


The Wright brothers launched the era of aviation on December 17, 1903, with a 12-second flight. Since then, aeronautical engineers and market innovators have made the experience safer, faster, and much more affordable.

For example, in 1970 the price for a roundtrip ticket from New York to London was $550. Blue-collar workers at the time were earning around $3.93 an hour in compensation (wages and benefits). This suggests a time price of around 140 hours.

Today, the ticket price has dropped to around $467. Blue-collar workers are now earning closer to $36.15 an hour, putting the time price at 12.9 hours. The time price has fallen by 90.8 percent: for the time required to earn the money to buy one flight in 1970, you can get 10.8 flights today.

Flying abundance has increased by 980 percent, compounding at an annual rate of 4.5 percent over the last 54 years. During this same period the global population increased by 4.3 billion (117 percent), from 3.7 billion to more than 8 billion. Every 1 percentage point increase in population corresponded to an 8.4 percentage point increase in flying abundance.

Now transcontinental flights are affordable for almost everyone. Free-market entrepreneurial capitalism isn’t about making more luxuries for the wealthy, it’s about making luxuries affordable for the average person.

While it is true that the 1970s flights may have had roomier cabins and better dining, flying today is dramatically safer. The Aviation Safety Network tracks airline accident data. Revenue passenger kilometer (RPK) is a standard metric used in aviation. Using this data, Javier Mediavilla plotted the ratio of fatalities per trillion RPK from 1970 to 2019 using five-year averages. The ratio decreased by 98.76 percent, from 3,218 to 40, during this 49-year range. Flying is more than 80.4 times safer today than in 1970, and safety has been improving at a compound rate of around 9.37 percent a year.

Considering both the time price and safety, flying has become 868 times more abundant since 1970 (10.8 x 80.4 = 868). If there had been no innovation in flying since 1970,  New York to London airfare would be around $5,059 today. Only the rich could afford transatlantic flights in 1970.

The 3,442-mile flight takes around seven hours. The supersonic Concorde could fly it in less than three. While there are no commercial supersonic flights available today, Boom Supersonic, a private company based in Colorado, aims to bring them back to US airlines by 2029. Perhaps spending half as much time on flights will allow people to use their most valuable resource for other value-creating activities.
