Most seasoned engineers that I know of in the field make in excess of $200k/year and they retire as low millionaires.
The point is that $120k in lost wages pales in comparison to the financial security a degree can provide assuming that one has the appetite and ability for that kind of work. UH and HCC get a lot of grief, but it's a reasonable school that produces good people.
Most professions require a degree either by legal mandate, or by essence.
