In the not so distant past, people didn't work hard, but not for the reasons many think. There were no happy peasants laboring a few hours in the fields and spending the rest of the day in leisure. They were starving and had no energy to work.
The average 18th-century Englishman got fewer calories than the average individual living today in sub-Saharan Africa. Because they couldn’t eat, these poor Englishmen worked little. Deaton writes:
The small workers of the eighteenth century were effectively locked into a nutritional trap; they could not earn much because they were so physically weak, and they could not eat because, without work, they did not have the money to buy food.
Johan Norberg in his book Progress reports the research findings of economic historian and Nobel laureate Robert Fogel:
Two-hundred years ago some twenty percent of the inhabitants of England and France could not work at all. At most they had enough energy for a few hours of slow walking per day, which condemned most of them to a life of begging.
And then, everything began to change. Deaton explains:
With the beginnings of the agricultural revolution, the trap began to fall apart. Per capita incomes began to grow and, perhaps for the first time in history, there was the possibility of steadily improving nutrition. Better nutrition enabled people to grow bigger and stronger, which further enabled productivity to increase, setting up a positive synergy between improvements in incomes and improvements in health, each feeding off the other.
