The problem with blanket attacks on capitalism is that it ignores the fact that the US became an economic superpower under capitalism, and we built the strongest middle class in history under capitalism WHEN WE MIXED IN SOCIALIST PROGRAMS.
BASIC economics shows that BY FAR capitalism is the most efficient way to generate wealth.
It sounds profoundly ignorant to be against that system.
Instead, we should be talking about what to do with the wealth it generates.
Bernie Sanders “Democratic socialism” is actually “capitalist socialism”. It leaves in place all the profit incentives and machinery of innovation and production, but then it redistributes wealth away from the hoarders at the top, and gives it back to the workers who generated it.
This is a much more compelling system to fight for than just a blanket “capitalism bad!” argument.
