Truth is that there is some people motivated with money and some that are not. So there are different motives for success in people, saying that it it is not motivated by money is true in some cases
I am not totally disagree with your opinion, but as you can see without the money do you think we can actually survive in this world? The food, water and also shelter we needed everyday is not actually free. Even the government can't actually provide for those people who actually needed some help. That's why we are all motivited by money in order to help ourselves not to become helpless in the future.
