The income gap is receiving much attention lately as more Americans are isolating themselves around "people like us."
More accurately, they surround themselves with people who earn similar incomes, and it is now fueling a rise in residential segregation. One recent study suggests the income gap might be greater today than even during colonial times – even when you account for slavery.

For many years — perhaps even decades — Detroit has been the poster child for economic malaise. Adjusting for inflation, per capita income in metro Detroit dropped more than 20 percent between 1999 and 2010.
Some analysts say regional cooperation might have helped keep Detroit above water when the car industry sank, but that entrenched divisions that pit the city against its suburbs, and blacks against whites, have hindered that.
