corralling student attention in the hands of the parents

What does this mean?

Also, I don't necessarily disagree with what you're saying ; the people in control of schools across the U.S. should be ashamed of themselves. However it is the responsibility of the parents to not just shove their kids in front of a screen because they're too busy for them.

Teachers have it hard enough as it is, I have nothing to say on that front. I would never have the patience to go through what teachers go through, period.
