Of Note:
-China not being as large a spot for manufacturing means the rust belt is not all that rusty. But India and Japan/Korea pick up some of the slack, so decline is still there.
-The aggressive environmental policies of the Gore Administration mean the Appalachians are even more screwed than OTL. Combined with the general improvement in the rest of the country the region is seen as 'America's Secret Poverty' (similar to the OTL Singapore problem).
-The fact that Reagan never happened means the government and associated industry are even bigger than OTL (not to mention the Cold War), so the region surrounding the capitol are extremely developed. D.C. proper is basically Monaco on steroids.
-More renewables mean the Dakotas and Texas aren't doing as well.
-Silicon Valley is much bigger, again due to China. Also because corporations don't move into Utah.
-Lots of Black Belt areas are a lot better off, thanks to Jim Clyburn (Speaker of the House for over a decade). Although this is often not visible in income, as the long term benefits haven't fully come to fruition yet.
-The rest of the country is generally better off thanks to a stronger safety net.
