The latest revision from the Dept of Labor has significantly revised the 2011 Atlanta employment figures upward indicating growth and recovery. I don't dispute the fact that Atlanta was harder hit by builders overbuilding and banks extending loans to people who had no business buying homes.
However, the answer to the question is more closely tied to simple supply-and-demand economics: There is an oversupply of beautiful women in Atlanta working in the escort business, and when supply increases, all other things being equal, price decreases. This economic fact is further compounded by another economic fact: when the economy turns down, more women enter into this business and at the same time the men, again because of the economy, have less to spend. Both factors working together drive the average escort price down.
So, it really has nothing to do with men in Atlanta being "cheap" as one or more have indicated - it is just an economic fact that if a commodity is available at $275, why be an idiot and pay $400, $500, $600, or more for the same commodity? Granted, there are a few Providers that differentiate themselves in the higher price points, but not all who ask that price have anything to differentiate themselves that warrants the price delta.
