There are only a few reasons why all 5 of the richest counties in America are right outside of Washington DC. We can first know that it is not because of any job growth industries, when was the last time you saw something that said “Made In Washington DC.” lol. My guess is that its because we pay politicians TOO much money, and the lobbyist who bribe them have TOO much money. While the rest of the country has been in economic turmoil the richest people have moved closer to the power center, to make sure they are getting legislation passed to protect their wealth, while the rest of the country suffers the consequences.
