What does it take to earn one's way through college? From the Atlantic, some stunning numbers:

[Olsen] added a linear regression analysis to extrapolate the stats for 1979-2013, and found that the average student in 1979 could work 182 hours (a part-time summer job) to pay for a year's tuition. In 2013, it took 991 hours (a full-time job for half the year) to accomplish the same. And this is only considering the cost of tuition, which is hardly an accurate representation of what students actually spend for college. According to the College Board, average room and board fees at public universities today exceed tuition costs by a little more than 100 percent. (For the current academic year, average tuition at 4-year public schools is $8,893, but with room and board, the total average cost comes to $18,391.)
