With eight kids, you aren’t going to save a lot unless you’re outrageously successful. It’s smarter to encourage independence and if that doesn’t work, plead poverty so your kids can get college at the wholesale price.
I was fairly fortunate in business and paid full boat for three kids. Eight? Couldn’t imagine it.
This is precisely the problem with the expectation that parents should pay, it isn’t scalable. I only had one child so I assisted with his tuition needs, although I wanted him to have a stake in the game...so not all of it.
Given the price of college, along with all the useless degrees out there, many would be better off buying their kids a house. But nobody expects that do they?
