We give children close to zero financial autonomy, no idea of work, of making money and losing it, then ask them to make one of the largest financial decisions of their lives at the age of 18. The background to this is a massive amount of messaging that your education is worth it.
It's not surprising they feel this way.
For the record, I didn't go the traditional college route, and I never had a penny of student debt, so if anyone has a right to feel smugly superior, it'd be me. However, I only avoided student debt by the dumb luck of making poorly thought out decisions that happened to work out in the end.
