Negative, plenty of poor immigrants (and natives for that matter) instill a strong regard for education and personal responsibility including my own family.

And this still does not solve the problem of access to the internet (through which formal education is being delivered) or this idea of parents being able to both work to support their children and somehow replace this online formal instruction with homeschooling.

No, not negative. It's an empirically proven fact that children of wealthy parents perform better in school. This is not up for debate.

I don’t think anyone was denying that...

What I read was a repudiation of the argument that on average poor children fare worse in school therefore a given child from a poor family will necessarily perform poorly. It is entirely possible for a poor child to outperform wealthy peers, and the behavior of that child’s parents or the culture at home may have a large effect on their performance.

Is it because they are wealthy? Or how about, how much of the difference (not quantified here) is because of wealth?

> "Culture" seems to be a byword for money here.

is what I'm disputing, which would imply that money will solve our problems.
