As it turns out, "moving" is exactly what my parents did, and to my benefit, when I was in first grade.
Luckily for me, my parents were in an economic position that allowed them to make that move. I think we need to consider the issue of income inequality as we think about that "just move" advice that Chetty is providing. As Bernie Sanders has been saying since 2016, and before, we need to rearrange our politics to redress that 1% / 99% imbalance that is the real cause of many of our problems.
There are a LOT of wonderful parents out there! Let's make sure our political decisions give them the economic wherewithal to "make the move" that can change their family's future!
