“Highly-educated urban” parents would likely be sending their children to private school, costing a fortune (in addition to the taxes they’re paying for the government system) and taking a lot of parental effort. A little common sense would show that homeschooling, especially with some professional classes thrown in, would save them money, time, and hassle.
Yeah, but THEY would have to deal with the little brats instead of shipping them off for someone else to take care of while they, the parents, seek their “me time” and “self-actualization”.
