I really could not care less whether this guy pays back his loans, his parents pay them, or they all ultimately become defaulted.
The system we have is complex and economically incoherent. The vast majority of people have literally no hope of understanding the first and higher order effects of the reckless provision of credit to or on behalf of young people, many of whom should not be in college in the first place.
There is no moral issue here. If the laws allow you to delay or ultimately avoid paying your college debts, and you are willing to live with the legal and financial consequences (which are often overestimated anyway), I say go right ahead.
