You are right about that, Stan. #4 is really more for those who live in Red states who can apply pressure on their Governors. In the longer term Red states could become more efficient (much room for improvement there), and adjust their out-of-state tuition downward. Perhaps special out-of-state rates could be done for bordering states.
All this is more for undergraduates than post-grad students. Why incur $50,000 to $150,000 debt for the first four years?
Then, lets cut back on this silly notion that everyone now needs to get a Masters degree. Some need it, but for many it is just a "deep-freeze" where excess undergrads are stored.
