I was just saying that technically education is not a public good, because it is not non-excludable, ehh, that is alot of negatives, sorry. How about this: Education is excludable, therefore it is not a public good. Whether it should be provided by the public (government) is a different matter.
You went to GMU? The bulk of my econ professors went there. Nikolai Wenzel and Nelson are quite young, but maybe you know Ivan Pongracic (foreigner). I do not know if Gary Wolfram and Charles Steele went there, but maybe. I also know Nathan Russell from GMU, but he teaches elsewere.
Any of those names sound familiar?
