Here's the government's current unemployment rates by best 10 and worst 10:
|Unemployment Rates for States|
|DISTRICT OF COLUMBIA||8.5|
At present, American prosperity is dominated by natural resources per capita, with low population states with lots of energy resources in the ground and not too many workers (i.e., not too close to the Mexican border and Mexico's "reserve army of the unemployed" and not too tied into global immigration) having the lowest unemployment, and highly urbanized states having the highest unemployment.
Hopefully, this won't always be true. But, it is true that one of the big drivers of America's heritage of prosperity has been having a lot of valuable land per inhabitant, as was pointed out by Benjamin Franklin in the 1750s.
The more recent notion that American wealth doesn't have anything to do with having lots of wide open spaces seems to be mostly the product of the neuroses of the kind of economists who feel uncomfortable in the wide open spaces and, especially, feel uncomfortable around the kind of Americans who feel comfortable in the wide open spaces.
