They shouldn't support it because the point of the government is to act on behalf of the society as a whole. Many problems need money: healthcare, transportation, energy, disaster prevention etc. Without the market's price mechanism, in this context represented by the job prospects after graduation, it's very difficult to know how much should be spent paying philosophy and gender studies teachers. We'd be preventing an efficient allocation of resources potentially killing people in the process. Additionally, while many people have a genuine interest in these topics (and should buy themselves books, or pay their own philosophy college course), many young adults will be happy signing up for this "education" to avoid making hard decisions for their lives (such as getting a plumbing degree). In this case, the government is financing a sort of young adult daycare and party service.
