I disagree. Family education is very important, but it’s not something you can rely on. Just to point out some major problem:
you leave behind everyone that have a problematic family
even the most intelligent and benevolent parents will be just limited to their core value and experience, and education needs more
education is a very complex process that needs professionals, especially considering a rapidly evolving context like today. You can’t ask a parent to be ALSO a professional educator. You need skills, training, experience.
