> which means better funded schools

This is another problem - school quality influences real estate valuation. If I support my local school and it gets better results, not only I can claim tax credits for donating to the school, but I also increased the value of my house. Or a house near a school I support.

Donations to support schools should always be equally divided among all schools, period, so that these donations can't create favored and disfavored regions. That public schooling should be both universal and uniform should be a given.
