Oddly one area where earning a degree is worth it is religion. If you graduate from a Seminary, Theological School or Yeshiva in most faiths you are assured a job and usually a salary. A starting Rabbi for example can walk out of a Yeshiva and earn an average of $50k a year. A Priest usually gets their education for free and a career, if they reach full ordination and are in high demand even with the obligations. These may be soft degrees but appliable to a real career if one is serious about serving others and studying for this.
Even a soft degree to a gifted student is not a waste a high performing student in the arts with the talent and who can make it work is not in a bad major say a Theater or Music program, it depends on the student. And sorry but we need academics maybe not tons of them but genius is of value even if in philosophy that can lead to other things writing, legal studies, academic careers and the like even if not big money makers. I would say if the student is on an academic scholarship and doing very well and not going therefore to have a serious debt the budding scholar being a scholar is fine. Or if a student is older and pays their own way its also a good thing to study what you like. A degree in and of itself has some value and some people might be more into advancing knowledge and the like over making money that is not bad.
Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for the others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish for ever. - In Praise of Idleness, Bertrand Russell, (1932)
