Anyway, this is more personal experiences, but I'd say I'd pay a good bit for a haircut. I could cut my hair myself, but that would look pretty horrendous. I'd also pay high prices for good, high-quality chocolate because that stuff is the BOMB and I can't make it, and same thing for an Italian style pizza. I'd also pay high prices for doctors because they help keep you healthy and can alert you if you have a serious illness. I'd also pay high prices for internet and power because in today's society those are some of the most necessary things in the US of A.
Anyway, I'm just spouting. What about you?
