> But it boggles my mind how people can assume, with a straight face, that they are equipped to educate their child alone - something which is normally a profession for which you have to study O(years) (and even then most people aren’t really good at).

The key assumption here is that the expertise and years of studying translates to desirable outcomes. The large expansion of homeschooling suggesting by the article suggests a great rise in people who no longer believe that the expertise promoted by teaching schools is actually relevant to teach their children.

After all, mass public schooling is only about a century old and default human experience in many ways has always been closer to what we call homeschooling.
