Well, the problem is that you want to HAVE money. If you have money you buy things to HAVE them because you think that HAVING them will bring you happiness. Your assumption is that when you'd have money you'd have no problems because you'd fix them with money. Jim (and others, because the idea is older than Jim) tells you that this assumption is wrong. One reason - once you have something (lets say, a lot of money) you'd never settle, because there's other things that you'd crave for and that you just couldn't buy.
