> At least in/near any decent size city, there should be a large enough population to create classes of a reasonable size of same age students at roughly the same level. Why? There is great educational value in being in a class which has different levels. If you are smarter: learning to help others, working together with people that are slower than you are, learning that usually intelligence is not one-dimensional and kids that are not very good at math might be great at writing… If you are less smart the benefits are across the board. I remember reading a study about mixing kids from different incomes in the same school as opposed to wealth segregation (you might argue that smarts and wealth are not the same, but they are often highly correlated at least when starting out) and the conclusions were that there was no drawback for the rich kids, but huuuge advantages for the poorer.
