You mean higher educated adults had children who knew more? Wow, what a surprise!
A college educated adult is likely to speak to their children in a broader vocabulary than an uneducated adult I would think. It’s not about poor or rich, it’s about education and intellegence in teaching children and expecting them to know things as well.
You are SO right on. It’s just plain silliness to equate it to wealth. IMO, it’s a ploy to make redistributing the wealth sound like a good idea.
Bunch of hogwash.
