Yeah, I mean the UK sold their student loans to the IMF and tripled the price. Half of kids end going to uni, most don't make enough to even register to pay it back (and expires after 30 years). And if you're earning decent money your accountant/business can easily subvert many of the payments. Seriously risky investment. A national strike a decade down the line and they won't be able to cash or sell any of those debts
