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)
I dont really know what to say about this, but if they are not motivated by money, there will always be a need for money. Money answers all things. Lets take for example that youre an engineer or a scientist, you wont be able to produce or make any research if there are no funding available for you to do so. So money is always important. And yes, money is never the motivation, but the purpose is always to make money.
