One of those people in their late 20s or early 30s, or even mid to late 30s who has never held any kind of full time job, barely has a degree worth mentioning (usually in something assinine like
liberal arts or women's native's lesbian's studies) and is still trying to get juust a few more courses before they can start their PHD..... and
eventually retire at 75 with several million in student loan debts and never having worked a day in their life (aside from mandatory TA positions).
