How do you mean they end up with nothing? Don't they get their needs for which they spend money? What if everyone decides to do business? Who will be there to patronize the business? Nobody, of course. So, everyone can't do business, and not everyone has the knowledge to go into business.

For some people, the best way to make money for themselves is to work and earn, and they are very okay with that lifestyle. That is why you can see some people who are not supposed to have a business; when they try to set up a small business, it is so difficult to make it grow because there is no knowledge to help the business expand.
