I agree with you, and I think it's because we spend our money on technology. When you buy the latest gadget immediately, it just becomes obsolete. When you save up to buy the latest gadget, a better one comes out before you're done saving. So you get a better a gadget and have more money for more gadgets.

I guess a lot of people want to have the "latest and greatest" for fashion reasons, and credit cards are appealing for that reason. I did that in college and it took me like a year of having a real job to pay it off. Sadly, other people never do pay it off.
