Here’s a fun tool called Rich Blocks, Poor Blocks that overlays data on household income over city maps, showing you the differences in income within regions, cities and neighborhoods.

If there was a regional tax base, the size of Northampton County or Lehigh County, to pay for local public services, then people could actually have a debate about progressive taxation. Should the people who earn more money pay more of the taxes, and the people who earn less money pay less? I think so. But with all these different political boundaries, you can’t even debate that. The richer people are separated from the poorer people by an arbitrary political boundary that has no real justification.
