I believe the point the GP was trying to make is that there are differences between the type of poor choice exemplified by (no offense to your fiancee) a degree in artistic metal-smithing from a prestigious private institution, and by a degree in computer networking from ITT or DeVry.
With the expensive liberal arts degree, realistically you know what you are signing up for in advance. You will be getting a degree in something that you love to do and are willing to make sacrifices for. It might turn out in the long run that a more practical degree would have been better, but you know in advance what you are getting. To the degree that the university promotes the degree at all, I doubt they promote it as a great career starter.
With a for-profit, they are almost always selling the degree as a vocational training, or a stepping stone in a career path. Whats more, the big for-profits heavily market the degree to the point of TV spots and the like.
So the point is, a liberal arts degree is sold as "do what you love and get a degree" while a for-profit degree is sold as "start your career and increase your earning potential". If after taking the liberal arts degree, you find yourself unemployable and with loads of debt, you could still have gotten what you paid for. However, if after a for-profit vocational school you find yourself in that situation, you haven't gotten what you paid for at all, in fact quite the opposite. The bad choice was different. With the liberal arts degree, the bad choice was pursuing a liberal arts degree, and it should have been made with a decent degree of fore-knowledge of the likely down-sides. With a for-profit degree, the bad choice was trusting the for-profit marketing materials when there may not be as much information about the potential downsides available.
All this sidesteps the issue of who the two degrees accept. I'd bet that the artistic metal-smithing degree took a lot of work both to get accepted and to complete the program. The for-profits on the other hand have a reputation of accepting almost anyone with a pulse and a student loan.
