In the 50s/60s/70s at minimum wage you used to be able to pay for a whole school year with 109 hours. Now, at minimum wage, just for 1 year is around 2250 hours. That's 13 months just to pay off 1 year of school, not including any living costs.
While I realize that's still a little more than 2x the amount of working hours, it's definitely not as depressing as 20x the amount of working hours as the poster stated.
