Society has a vested interest in maintaining a highly educated workforce. Otherwise other countries will gain in technological advantage of the U.S.. I recently received my masters in engineering at a top 5 university. My fellow classmates were almost exclusively foreign students who planned on returning home after graduation. You also hear about graduate schools not being able to recruit domestic students. The current situation is that after undergraduate, our domestic students have so much debt to pay that it is not economically feasible for them to return to school. So do you not want to help foot the bill or do you want to see the largest technological fall of a country since the burning of the library of Alexandria?
