I've definitely considered it. However, interestingly, to attend university in the USA usually carries a pricetag of $20,000 to $30,000 per year minimum after all the smoke and mirrors of "grants and financial aid".
So, you have consumers (students and their parents) paying real money for a real education that they are hoping will result in gainful employment. Either millions of students are overpaying every year, or the system provides some value.
Now, the ones delivering that value (grad students) are receiving maybe $8,000 per semester while teaching 100 students lets say, while the students are paying collectively nearly $1,000,000 for 4 months of tuitoon.
Where does the other $992,000 go, besides administrator salaries and football stadiums?
