In a perfect world, mom or dad would be home to spend hours after hours teaching the child. Not in our world today. Millions of both moms and dads have to work to make ends meet. What if mom & dad have a marginal educations themselves. Have to pay tuition to attend parochial schools and Christian academies. I know, paid 12 years of tuition to the local Catholic school system, it wasn’t cheap. It was worth the money though, and I could afford it. Not much money, little chance of a good parochial education, it is not free. The church schools and home schooling are viable options for hundreds of thousands of students every year, no doubt about that. But there are millions of children that require education every year, your model will not work on that scale. Public schools do work, when managed at a local level and reasonably funded.

If Catholics can do it Wichita, then Christians and Jews across the U.S. could, too!
I attended tuition-free Catholic elementary and high school. They were funded through donations to the parishes and staffed by volunteers.
It wasn't a perfect world then.

Where is the evidence that government schools work? Really....Where is it?
No studies have ever been done on so-called “good” government schools to determine how much after-schooling and private tutoring is done by the child’s family in the HOME.
By the way....homeschooling is in the MILLIONS. Private schooling is, too.
