Not surprising. Lots of kids are holding out hoping that someone will get elected and wave a wand to magically erase the money they borrowed.
You've got a great potion for disaster here: 1) You can't be denied an education loan. 2) Education loans can't be wiped out in bankruptcy because 3) You can't repossess an education. 4) Because of the above factors, there's little incentive for colleges to keep cost of attendance low.
I have no idea what the solution should be, but this problem can't continue indefinitely. It's a more complicated issue than just, "Millennials are just looking for handouts and don't want to pay their debts."
