Most public school funding that comes from the state, is based on enrolment numbers. Pulling just a single kid will cost the school dept a few thousand dollars in state funding. Enough people home schooling would literally defund public schools.

Exactly. Those of us who can't afford to do this have our children left all alone in public schools with the children of lefties. Ugh! Can't win until the system is overhauled or a voucher program happens.
