College costs way too much

I think it would be nice to live in a country where we didn't need so many student loans. Like many other people in the US, a majority of the debt my husband and I have are from our student loans from the mid-90s. Yes, we've been paying these for over 10 years now. And the payments on them are so outrageous that we aren't likely to have them paid off any time soon. Why does college have to be so expensive?
