Ah, so desu-ka! I get you now.
I don’t buy that argument, because social progress would never have happened in human history if it was valid. We did free the slaves, all over the world, and we did forcibly vaccinate my entire generation of children, and we did many other things simply because our cultural values and physiology both include fellowship with other humans.
I think my own decisions could be said to show why millions of parents have to be offered a better choice than the current system. Right now they have a choice of a crappy education or a crappier education, and wisely the most educated will choose the former for their children.
But we can afford to give every child a better education than my kids got. And I’m giving a specific prescription, based on real world experience, of how to do that. Make the comprehensive public schools the best schools, and make attendance mandatory. Humans have had compulsory education since as early as 400 BC, and even compulsory military service, this is not something new and unacceptable or unworkable.
If there are enough teachers, discipline is less of a problem, lack of personal instruction time available to less prepared students is less of a problem, inter-student conflict is less of a problem, grades and competence go up for all students, in fact all the most pressing problems are decreased in a way that does not exacerbate and enforce economic discrimination that is harming us.
If you have a better idea, I am all ears, of course. But the current system is unsustainable; it is getting worse over the time I have been observing it.
