Some West germans still look down on Ossies, even though Merkel was one herself. It's a lot like how northern states look down on southern states in the U.S.
The cure for this is immigration, but the people that remain in the rural areas are very right wing and very xenophobic.

"Average Wage in Germany by County
Notes: Average daily wages obtained from a 50% random sample of establishments via the Establishment History Panel (BHP) of the Institute for Employment Research (IAB). Real wages are expressed in 2007 euros valued in Bonn, the former capital of West Germany, using county-specific prices. East–West border is drawn for clarification; there is no border today."
IIRC the discrepancy between population share and elite share for Ossis is even worse than for American blacks.
TL;DR: at the 50th percentile, net worth of west germans was ~40k in 2012 vs ~14k for east germans (in euros).
