But clearly, funding local schools from property taxes is a terrible idea. When rich people flee an area and leaves poor and disadvantaged (usually non-whites) behind, they get screwed twice: falling economic activity, and then falling funding for decent schools.
Bad schools breed disadvantage. You make it worse by turning schools into "gated communities" (e.g. charter, private schools), and consign everyone else to dropout factories.
A good way to buy social peace, would be to find a better way to fund state schools.
