I think it's because the Capitalists' vision is myopic. They focus on short-term profit and immediate gratification. Greed prevents them from seeing the Big Picture, which ultimately has to include the good of the many. They don't see the interconnection.
Adam Smith used the word 'education' EIGHTY Times in Wealth of Nations. He wrote "read, write and ACCOUNT" FIVE times. How many of our problems are the result of not having made accounting/finance mandatory in our schools since 1950? Capitalists cannot be trusted to explain Capitalism.
