Respectfully, with as flippant as employers can be with employees lives, a "good" parenting situation can become a bad situation in a matter of months. And that doesn't even cover scenarios where someone can become an only parent.
Ideally, it's a place our social safety nets would be better, but they're pretty bad when it comes to helping children right now in the US.
Fair point and I realize not everyone has the resources to raise their kids the way they want to, but I get the impression most parents don't even want to keep their kids away from this stuff, regardless of their financial situation. There's a lot more awareness and concern in tech-related places like this, but the majority of the general population does not seem to have a problem with putting an iPad in front of a toddler, I see it all the time- in fact probably more commonly with middle-class families than working-class ones.
