One simple reason why I think it may make sense to want more money is to do interesting important things. If you earn more money, the market obviously thinks you're good at producing things that sell. It's not perfect as sometimes the market (e.g. the people) prefers something rather stupid. However, in general, I think entrepreneurs are the ultimate redistributors of money in the society. I don't believe government is effecient at doing the same job: it doesn't care whether it wastes it, it always knows it will get its share (taxation is not voluntary) and it's filled with people who have no idea how to actually make a useful product. An entrepreneur earned his money by people voluntarily giving it to him for something they want. He knows what a failure is.

So yeah, I think wanting to earn a lot of money is great and no one should feel ashamed of wanting that.
