Biology degrees are needed for a LOT of graduate level education programs, but if you stop your education after a bachelor degree, there is very little employment opportunities needing a biology degree.
Psychology is a much needed field, and we need psychologists, but similarly, you must have graduate level education to make a decent living in the field.
Journalism is dying, there is so much opinion and entertainment out there, but so little actual journalism.
This country NEEDS more journalist, psychologists, and "liberal arts," it's a shame that they can't earn a respectable living, and it's a shame these fields are undervalued by our society.
