Funny you forgot students still get different education resources from home.
When schools are equal, other factors become more significant. I think the next steps are:
- ban private tutoring
- ban zoning, not sure how this is going to work
- ban educational books from the market, so all educational books are equally distributed through public libraries
- wait, parents can still teach their kids. This is not fair. We also need to ban parents from teaching their kids. For an equal society, programmers should not be allowed to teach their kids programming.
- etc.
