Tbf, schools are sort of indoctrination camps.
That said, getting rid of school so that kids would end up learning 0%, instead of the currently 50% useful stuff* isn't exactly gonna solve problems.
(*since the other 50% is indoctrination)
The far right doesn't really want to get rid of school, they just want to control more of it so that instead of the 50% center-right indoctrination, it'd become 100% far right nationalist indoctrination with their agenda instead.
