In 1876, bananas were first introduced to the United States public through the Philadelphia Centennial Exposition of America. They sold for 10 cents apiece.
Let's look at a couple of miracles of market capitalism.
First, look at the map below showing all the countries where bananas are produced for consumption in the U.S. Why would anyone living in, say, Honduras, who has probably never met a U.S. resident and is likely to never do so in his or her life, ever spend their time and resources growing and harvesting, and then shipping, bananas for our pleasure?
Second, adjusted for inflation, the price of bananas in 1876 would be about 1.8 U.S. dollars today (i.e., $1.80). And yet I went to the store the other day and paid just 55¢ per pound of bananas, getting nine bananas for $2.14, less than 24¢ each. The standard of living in the U.S. increased roughly eighteen-fold since 1876, but the price of bananas increased by only about 2.4 times.
