theres 6 billion people on earth and I’m guestimating that theres only 200 million that support capitalism, 150 million in the US
Your guess of Americans is wildly optimistic. There are probably 200 million ordinary Chinese who love capitalism and probably just as many citizens of the rest of Asia and Africa. Why? Because many of these folks are peasants and working-class who have seen their lives improved throught their own hard work. In the past, my most productive employees were studious kids from Nigeria, India, Ethiopia and Korea. Not only did they work overtime, but several started their own businesses with family members.
Many Europeans and Americans are constantly looking for an entitlement or susidy while professing to be capitalists. So that’s why I don’t believe your 150 million number. As others stated above, I’m surprised it’s popular anywhere, given the constant propaganda.
Obviously there are a lot more than that who make their living from capitalism, but don't understand the process at all; for them, the wealth around them might as well have been created by pixies and goblins. This is the base of socialist parties like the Democrats, British Labour, etc.
