But that is how some working class people make enough to sound their kids to private school. Working their tails off.
I see that they have to do that as a moral failing of capitalism, both that public schooling is insufficiently good for their children and that a worker's base wage is insufficient to provide for that worker's child's education.
I mean your child gets an education either way, its do you get top 5% private school or public school? You can't give everyone free access to a top private school, or it is no longer a top by definition ;)
