The residency programs didn't give us that debt, nor did they take away our interest subsidies. Regardless, PAYE can make the payments manageable.
I know it sounds completely unfathomable to you, but there's plenty of nurses, police officers, teachers, etc, that manage to have children, a life, other interests, hobbies, and retirement contributions on 55k a year, particularly if they've got a partner that is earning similar to them. Yeah, it sucks that you can't really start doing the things you'd like to do until residency is over, but that's life. Yeah, the debt sucks. Sure, things could be better. But this is what we signed up for, and honestly, it could be a lot worse.
Because I'm saying it's all relative. Relative to most everyone else, we don't have it all that bad.
