On November 9th, 1989, the Communist German Democratic Republic declared the lift on the travel constraints between the East and the West. The two countries reunified less than a year after the Berlin Wall was torn down, and while many of the social and economic gaps have narrowed, there are still differences where the two countries existed. Steffen Mau, a sociology professor, states that while the West Germans would say there is little discrepancy, Eastern Germans say there is a striking difference between the two. According to a survey, more than half of East Germans said they feel like second class citizens. While salary disparities have shrunk, there is a lack of bigger, better paying companies in the East.
