To be fair, if you've only had the one boss, 100% of your bosses feel the way your current boss does. There literally aren't any other examples in your work history that you can use to prove (to yourself or to others) that your boss is unreasonable or incompetent.

I also think undergraduate programs could do a better job preparing students for this sort of problem. You don't learn except through experience or maybe good mentoring that chronic crunch-time-to-meet-deadlines is a management failure, not a sign of developer incompetence.

But, yeah, I agree that bosses exploit young employees.
