:/ capitalism works.
But there should be a limit on wealth. As-is there are extremely wealthy people that can have more money than they can possibly spend. This is a problem more so that the more people become on this planet the more rich people there will be. The same goes for poor.
Socialism.......causes many problems. The ONLY way it can work is for the entire population to agree on everything, which if you've seen humanity, will never fucking happen.
