I don't know whether to laugh or cry at the ignorance of this statement.
Glad to meet you, Andy. I'm a non-homeschooled, successful guy too. There aren't too many of us. /sarc
Laugh or cry? Well it depends on whether or not you are a government teacher or someone sucking a living off the government school teat.
As thoughtful conservatives think about this statement ( “All academically successful children are homeschooled”) they will begin to see how true it is.
They will begin to compare the home life of the academically successful homeschooled child and that of the academically successful institutionalized child. They will realize that the pre-school experiences of these children are essentially very similar. The time and effort spent by the parent of the institutionalized child in supervising homework is about the same as homeschooling. Later both the schooled and homeschooled child gradually take over more responsibility for their learning. The vast majority of this learning happens at home.
By the way, I have been a health professional nearly all my adult life ( except for the 8 years I homeschooled my kids). In **every** case of an academically successful institutionalized child, the parents reported to me that their homelife and home education experiences matched those of homeschoolers. This is true even in immigrant families with academically successful children. These immigrant parents reported that they found someone to mentor their children. Often it was an older cousin, aunt, or uncle.
Are there exceptions? Hm?...Maybe. If they exist they are very rare.
Just watch. You will see that this idea will catch on and it will be picked up by major conservative editorialists.
