So I am one of those that were saying go STEM or business in the other post. My main point was that you need to evaluate the time and money trade-off of a college degree vs the payback potential. That is why a BS in psychology is not on the good side of the trade-off evaluation. I promoted STEM or business as a better choice to stay on the positive side of that trade-off.
I fully support and encourage the trades route as alternative to traditional college. However, my impression (of course limited to my view) is that most liberal arts type majors are people that also would not like doing trades type work. So saying trades as an alternative for a liberal arts type person is not really doing them any good as a suggestion more than saying go STEM. Either way won't work for them.
As for what is my suggestion if not STEM or trades? I would say business, or nursing. Nursing is tough, long hours, work holidays, and requires dealing with patients, doctors and families. It's not easy. My DW is/was an RN, so I know first hand what she did.
If a kid is just set on being liberal arts, then the path I would suggest is teaching. It may require more degrees beyond BS. Minimum will need to get teacher certification. Again not the easiest route, but at least will have some better potential. If teaching is not the route, then the kid better be good with people and go into sales. Has high income potential, if good at it and have a good product to sell. Selling to public is a hard way to go, get into business to business sales. Freelance pharmaceutical sales on the corner may be very lucrative, but usually ends bad.
I agree completely that as society in general we have made traditional college as the path expected and have led too many kids down that path without a sense of what they want to do once done. A degree is a good thing, but is not a good financial trade-off if that degree does not have decent payback.
