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 am totally agreed to this statement but, nowadays, most of the people are more concern to money than anything since money is the most important factors in our lives, it is the one who provides our life. We work because we want to give our family a better life, we want to give them their needs as well as their wants. Therefore, there is no problem if the people will motivated by money because it is one that we need to we work for.
