Absolutely. A form of this thinking has already taken place here in the US. The decay of our inner cities is not blamed on the people who live there who have made DC, Detroit, etc into uncivilized hellholes. The decay is blamed on "white flight".....in other words, they fled for their lives (often losing all of their property equity on the way out the door), and left with their paychecks too. Now, without a tax base, the parastitic populations and city governments no longer have anyone to loot.
