This is going to start an interesting circle. People can't get a loan so they don't enrol. The colleges rely on numbers for funding, so their funding gets cut. When funding gets cut, programs get cut, so there are less places for students. If there are less places, people can't enrol anyway...
The only upside I can see is that it might force people to focus on why they want a higher education, rather than drifting into it, amassing a huge debt, and then graduating in 4 years with a degree they don't intend to use, and don't really have any interest in. I think college is the default for a lot of unfocused Gen Yers, and most of them have no concept of why they're there, apart from delaying real life for a while. Not true in all cases, but certainly in a lot.
The other thing I'd really like to see is the powers that be focusing on chanelling more people into professions where bodies are needed. We have too many lawyers and accountants? Make law and accounting expensive - and subsidise the hell out of med school, nursing and the trades to attract people into those areas. Some of the institutions are SO short sighted, it makes me boil...
