It's partially their fault for getting a degree in a saturated field that either doesn't have the demand or the skill set that pays more. Before I got into Aviation I was making $70-86k depending on if I worked overtime. That's without a college degree working alongside people who have to use their fingers to count to 4.
They can't expect to be a social worker and make bank. If they're going to take on debt to get through school they seriously need to examine their prospects first. Just saying.
