Add in the fact that you can go to a super cheap college or super expensive college can totally change the ROI numbers and its 90% on the investment side not on the return side.
The blanket statement of college is or isn't worth it doesn't work anymore. You have to be more specific.
If you go because you need the degree to be effective(Doctors, Lawyers, Engineers, STEM) then the degree only gets your first foot in the door. Its been my experience that every job after that cares less and less about your degree but your still have to have it.
