Wealthy people will always have nicer cars and better vacations and bigger houses, but that doesn't mean the children of poor people should be relegated to terrible schools where they'll have no future.
Don't forget that part of being an involved parent and making sure your kids get a good education is, critically, getting them in a good school.
Yes, family education cannot be fully replaced by school instruction. But the reality for many struggling families is that they need as much help from the schools as possible.
I'm very pro-family but I take issue at the wealthy who point their fingers at struggling/broken families who haven't been dealt the same cards in life, and justifying blame by judging their lifestyle.
further, we spend more per pupil than other developed countries that are delivering superior results.
