Plenty of children suffer in public schools as they are currently constituted. School vouchers, school choice, and attacking teachers unions are attempts to create more schooling options than just whatever the local public school is, which should benefit children who are currently having a bad time in that system.

School boards are inherently poltical because as long as a publicly-run school system exists, how it is run and what things it will attempt to teach are political questions. There's no apolitical school board that existed 40 years ago that has been altered since then, they have always been poltical.
