Money let's you trade things you don't mind doing and stuff you don't need for things you want other people to do and stuff you want to have. Clipping coupons can pay 1000$ an hour or 1.5$ an hour but the important thing is not just ROI but how much you like or dislike doing things. But with stuff there is a third option. I don't listen to music so the cost of a CD or concert ticket is irrelevant to me. I don't like to travel so the cost of a plane ticket is irrelevant, I don't like posters, nick nacks, or buying clothes so most stores simply don't have anything I want to buy.
So, when you see someone that saves most of their money don't assume they are hording it, some people just don't find all that many things they want to trade it for at a price they are willing to pay. Now I like playing video games, but I have several of them unopened new in box so I don't feel the need to buy yet another one that may or may not get played etc. I have cable TV, but I spend far more time playing free flash games not because they are cheap but because I simply enjoy them more. http://www.kongregate.com/games/light_bringer777/learn-to-fl...
