For hundreds of years, economists have debated whether population growth is good or bad. Malthus said exponential population growth increases labor supply, so wages fall until starvation, war, or plague stops growth in numbers. Marx said capitalism causes poverty and hunger, so population growth is good, because “every stomach is born with a pair of hands”, bringing revolution and justice closer.
Nearly 200 years later, Garrett Hardin and Julian Simon were still debating the same question.
