Why don't more people who plan to be stay at home parents. consider getting a degree in education to be better equipped to home school their children?

if your plan was to be a stay at home parent would it not make some since to consider a degree in education and/or early childhood development. so you could better equipped to homeschool your children or tutor local children.

also if a group of parents managed to do this and each got degrees in field education fields. they could each teach all the children from the verse families a different topic. so it would be a localized school of sorts with people you trust to teach your children life lessons. kind of like how it once was before the government and teachers unions stepped in and took control.
