Bullshit

Capitalism at its core that you allow free trading. And. It. Has. Been. Successful. Capitalism is what killed the USSR by sheer force.

The problem arises when it's not controlled at all. Apply those rules well and you get a powerhouse generating huge progress for everyone and the taxes and all will be able to pay for the social security network on top of that ensuring nobody gets left behind

You can go to communism Island if you want and suffer under economic mismanagent, bit I'd rather have capitalism, thank you
