schools won’t improve until parents improve ...
Get rid of government schools. The GOP should push for School Choice. Allow parents to use money for private schools, parochial schools or homeschooling. THEN the schools will be as good as the parents want them to be. Bad parents will "save money" and send their children to bad schools. Good parents will send their children to good schools and those good schools will remove any bad children/bad parents from their student body.
Put parents in charge, not the government, and you will start to see some improvement.
