That is kind of my point. Outside of a few fields (some branches of chemistry certainly being one of the exceptions) will someone pay you to do your research.

I just pulled up the newest published math paper from arxiv. No one except universities will pay you to research "Quenched path limits and periodization stability for tilted Brownian motion in Poissonian potentials on Hd"

Just because your specific thing you are interested in researching has value to the free market, doesn't mean that all are so lucky.
