Interesting that no one's trying to argue against humanities being a bad choice in a poor economy. Instead you're trying to argue that the economy isn't doing too badly. Even the OP made the point that enrolling in these courses is something you do due to your own interests rather than for an economic reason.
So now take the uncertainty you acknowledge combined with the reality that yourself and OP acknowledge (even if implicitly) that humanities is not something you do for economic reasons and you have your answer.
If humanities could make a case that it's a good idea financially that might help enrollment but no on in this thread is even trying to make such a case. Instead the case being made is that you should do it out of passion, not for economic reasons. Such an argument won't win you any enrollments when things such as housing are unaffordable.
