If capitalism dies, mankind's ability to progress will die.
Not certainly, but capitalism has lead to a lot of competition in order to get a better, cheaper product and that's where the driving force for a lot of innovation in technology comes from. In this system, which there are a lot of flaws, it has worked better than our friends in the USSR and Cuba.
I think it would be best to continue to have a mixed market system, where some things are controlled by the government (schools, police), and others not controlled by the government (businesses) but needs to pay their fair share so everybody can prosper. Almost the current system we have now.
Capitalism is much more efficient than a mixed market system. The only reason we can have a mixed market system is because pure capitalism created enough wealth for all of these safety nets. Capitalism literally has no flaws.
Kids, this is why elephant dick is bad for you.
