If somebody is passionate about art history, then they should get a degree in art history regardless of job prospects. You are limiting their ability to get the education they want.
Now I will agree that somebody getting an art history type degree shouldn't be taking loans to get it, they should be paying for it out of their pocket. However we should not limit somebody from pursuing their interests just because their interests are not valuable to society.
