Education just changes the rules of the game when it comes to working time. In the US, once you have your college degree, you morph from an hourly employee where overtime is paid, to an 'exempt employee' where extra hours are unpaid.

Over the years, the federal government has added more jobs to the exempt employee list. This means we get things like fast food store managers making $26K/yr putting in 60 hour weeks. There has been a push to change the minimum salary to $50K/yr for exempt employees, but employers have successfully delayed the implementation of this till late 2016.

Ideally, the US needs to rewrite the Fair Labour Standards Act to be more in line with the EU working time directive which limits the working time to an average of 48 hours over a period of several weeks. This allows overtime to be used in bursts, but not chronically.
