Private and charter schools remain a good alternative to pubic schools. My kid is in public school and it is relatively neutral, being in an affluent suburb. The states and local governments must take back the public schools from FedGov authority. Their educational system should be tailored to the place they are. Does a Navajo child, a child on the Alaskan north slope and a child in the Florida keys need to know the exact same thing? No! Let the states decide, they are the ones under the constitution who decide what is taught.
Charter schools ARE publicly schools; they just aren’t run by teachers’ unions. The “regular” public school systems oppose them because they are funded the same way (taxes) so the old-school union mafia loses revenues - while simultaneously being publicly shamed by chronically underperforming a competing public school system.
