To understand the feeling of crisis that many see in higher education right now, it’s useful to start with some figures from 40 years ago. In 1974, the median American family earned just under $13,000 a year. A new home could be had for $36,000, an average new car for $4,400. Attending a four-year private college cost around $2,000 a year: affordable, with some scrimping, to even median earners. As for public university, it was a bargain at $510 a year. To put these figures in 2015 dollars, we’re talking about median household income of $62,000, a house for $174,000 and a sticker price of $21,300 for the car, $10,300 for the private university and $2,500 for the public one.
