Fortunately if you are homeschooling you can seek out specific teachers to help expand on things and choose those that are excellent. (Many homeschooler start taking community college classes in highschool if there are good options available.)
This is a sampling question.
Consider that you may be looking at a bunch of well-educated parents choosing homeschooling over extra income.
I bet they're not choosing to homeschool kids with whom they have a bad relationship, don't understand, can't motivate...
Increasing the sample could produce much different results.
Admittedly salaries for public school teachers are pretty bad. There's no FAANG school with tricky interview questions and starting salaries double of what other schools are paying. I wish there were. Then you might see those 10x teachers choosing "teacher" as their profession.
I also don't buy your notion that neuroses are directly transferable by contact. If anything, your kid will probably be so annoyed by them that they'll be exactly the opposite.
