I always hear the argument for capitalism "B bb BUT people won't innovate without the profit motive" WRONG
Humans want to solve problems, create, and innovate, they do not need money to motivate them. Cavemen were painting art 20,000 years ago without the desire of money.
True scientists like Tesla, he didn't care about money it was about the pursuit of science.
Capitalism does not cause innovation, most new technology is found by government programs like nasa (internet, smartphones, etc)
Main reason why they care about money because money can buy them everything in this world, that's why they need find job to get money and using that to sustain their life.
