Just for what it's worth, Australia has a taxpayer-funded student loan scheme (HECS) and the obscene fees you see in the US simply aren't a problem here. A full 4-year Electrical Engineering degree from Monash cost me about A$30k back in 2012. It looks like now they're around $40k. Even for an arts grad, this is something one could comfortably pay off in 2-3 years.
I don't know the specifics as to why this is the case, but it's clearly something that can work with proper regulation.
