In the Dark Ages when I was an undergrad, we lived in dorms with painted cinder block walls, spartan furniture, and a bathroom per hallway. We had a minimal gym facility but reasonable equipment in the labs. With some help from my parents and working had during summers and breaks, I graduated with only $750 in loans.
Now you have luxury dorms and sports complexes. Sadly, the cost increases for these facilities and the explosion of administrators made it practically impossible to pay for one's education at a top tier state school by working hard during the summers and breaks and some help from ones parents.
Let's not mention the Lake Wobegone mentality that all the children are above average. Colleges love remedial courses - they get paid and the students stay longer. But that changes the economics. Attending college is a business decision and if the graduate can't repay the debt in a few years, the ROI wasn't there.
