IMO most talented/flexible degree per year studied is electrical engineering.
Best degree is no degree though. One Vitalek or Bram Cohen is worth 10000 Harvard computer science graduates.
For the unicorns that can pull that off, sure. For the other 99.9999999999999% of the population of the planet it's really bad advice.
"Higher education" is mostly make-work for pedants and busy work for students; the result is pretty similar to what high school was 100 years ago. It's also a form of dysgenic population control, and a way of growing debt peonage among the more intelligent half the of the population, which is probably useful for social control.
I've considered trying to raise a bunch of little Vitaleks myself, just to see if it can be done. Cathedral scholar style. While his and, say, Bram's output is exceptional: I think one of the big reasons it was is they never went to college. Greatest individual systematic trader I know: same story -he never want to college either.
Also your sigdifs are way off. I bet you learned that in collitch. ;-)
If you don't mind being broke and living on welfare, by all means, get that liberal arts degree.
