It's cultural, I think. In the US, we are very consumer driven. We are bombarded with propaganda constantly telling us that the one thing missing from our lives is whatever that person is selling. Some of those people are selling credit. That wouldn't be so bad, except that Americans are also highly competitive. We hate losing, and someone else having more stuff than us is losing. Our entire measure of the value of a human being is their wealth.

Consequently, many Americans spend nearly everything they make on stuff that ultimately contributes very little, if anything, to their contentment. Since buying those things didn't actually make them happy, they figure they need more money, and more debt, to buy more things. It's a trap we've created for ourselves.

Oh, and our health care system is ridiculously expensive.
