Cordless Drills on Sale: Buy One, Get 41.8 Free

Since 1961, when they were first introduced, the time price of cordless drills has fallen by 97.7 percent.

Summary: Cordless drills have become much more affordable and abundant over the years, thanks to technological innovation and economic growth. Since its invention in 1961, the time price of a battery-powered cordless drill has decreased by 97.7 percent.


Technically speaking, the first “cordless” drill was the hand-cranked bit and brace drill, which was invented hundreds of years ago. You can still buy one of these classics at Amazon for around $57.

Black and Decker introduced the first battery-powered cordless drill in 1961. “It was a great advance,” Mr. Decker said, “but people weren’t prepared to pay $100 for it.” Blue-collar compensation (wages and benefits) in 1961 averaged $2.60 an hour. This suggests it took around 38.46 hours to earn the money to buy a cordless drill in 1961. No wonder it wasn’t too popular.

Black and Decker’s cordless drill made history in 1971 when NASA’s Apollo 15 mission used one to extract core samples on the moon.

Today you can pick up a Black and Decker cordless drill at Home Depot or Amazon for $29.99. Since 1961, blue-collar hourly compensation has increased to $33.39, so the time price for today’s cordless drill is 0.9 hours or 54 minutes. In 61 years, the time price has decreased by 97.7 percent, from 2,308 minutes down to 54 minutes.

For the time required to earn the money to buy one cordless drill in 1961, you get 42.8 today. Drill abundance has been increasing at a compound annual rate of around 6.35 percent a year.

You can learn more about these economic facts and ideas in our forthcoming book, Superabundance, available for pre-order at Amazon. George Gilder calls it a “supremely contrarian book” which overturns “the tables in the temple of conventional thinking” by deploying “rigorous and original data and analysis to proclaim a gospel of abundance. Economics—and ultimately, politics—will be enduringly transformed.”

Driving in 2021 Was 225 Percent Safer than in 1970

Deaths per traffic mile have decreased by 69.3 percent while miles per gallon increased by 95.4 percent.

Summary: Over the span of five decades, advancements in vehicle safety technology have contributed to substantial improvements in traffic safety. Meanwhile, significant enhancements in fuel efficiency have been achieved. If you define travel abundance as a combination of these two factors, then abundance has increased by 596 percent.


Between 1970 and 2021, the rate of traffic deaths for every 100 million miles driven decreased by 69.3 percent, from 4.88 to 1.50, according to the National Safety Council.

Vehicle miles driven increased 179.8 percent from 1.12 billion miles in 1970 to 3.13 billion in 2021. During this same period, the number of deaths decreased by 14 percent from 54,633 to 46,980.

If traffic safety hadn’t improved since 1970, there would have been 152,842 traffic deaths in 2021 instead of 46,980. That means 105,862 more people are alive thanks to better traffic safety measures. Adjusted for miles driven, for every traffic death in 2021, there were 3.25 in 1970 (4.88 ÷ 1.5 = 3.25).

The opposite of the death rate would be the life safety rate. If we index traffic safety at a value of 1 in 1970, the rate would be 3.25 in 2021. Measured from this perspective, 2021 was 225 percent safer than 1970. Vehicle safety has been increasing at a compound annual rate of 2.34 percent, doubling every 30 years.

Cars and drivers are both getting safer by getting smarter. Cars today have three-point seat belts, air bags, stability control, backup cameras, blind spot detection, anti-lock brakes, radial belted tires, headrests, tire pressure monitoring, automatic emergency braking, lane departure warning, adaptive headlights, adaptive cruise control, and anchors for child seats.

We also get much better mileage. The full-size Ford Galaxie took the number-one spot in sales for 1970. It got 13 to 16 miles per gallon. Today’s bestseller is the Honda CRV, which gets 28 to 34 miles per gallon. Gas mileage has increased by 114 percent while safety has improved by 225 percent. If you define travel abundance as a combination of these two factors, then abundance has increased by 596 percent.

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.

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:

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.
