Even if she was taking loans out to pay for school and living off the $90k, that's not horribly bad. Ok, in an online hit piece, it sounds bad and maybe it is. But blowing $30k a year with no job isn't great, but it's not insanely horrible either. Yes, budgeting is important. Yes, get a job.
Honestly do wish HS has at least one "real life" class per year. Simple car or home repairs, budgeting, etc.
