this is a very US centric view and problem... in other countries lower income does not correlate with no access to local grocery shopping school etc...
a german newspaper did a great income analysis of german cities [1]. You really see the differentiation in income, but if you overlay (at least for the cities I looked at) it with a map even in the low income neighborhood you get decent grocery shopping in walking distance (Lidl has also good organic produce/groceries) and schools and gyms etc...
I imagine the point is that what happens in the US isn't some inevitable state of things, it's the choices of US citizens, and they could look abroad to see counterexamples to their assumptions.
yeah it was meant in this direction... I lived and worked in Minneapolis and Boston and I don't get all the discussions why this segregation for livability, walkability etc is so prominent and by choice in the US compared to the cities in europe. I mean here you also have an separation by income (as indicated by the linked provided), but even the low income areas are livable and walkable and you have everything for your daily needs.
