"But the logic and practicalities of going bankrupt post training still hold good"
Seems to be a magnet somewhere near your moral compass?? and as such the likes of chris-squire suffer as a result of this sort of attitude as the opportunities that were available to others to finance their training are now not availiable to him. Shirking your responsbilities be they debt or otherwise strikes me as a cowardly and selfish way out of agreements you have signed up to in all but the most extreme circumstances.
Anyway this has been covered before many times and each individual has his/her own level of what they consider to morally acceptable behaviour. Just a shame others have to suffer the consequences through no fault of their own
