"Collapse of the Berlin Wall" is truly a sucinct way to express economic and social collapse after state border infrastructure was overwhelmed by GDR citizens' political wills...
Once celebration subsided and economics became a universal metric, disparity between the East and West halves of Germany became clear. To examine this, a wonderful starting point is the quote from former-First Lady Michelle Obama, "The the measure of any society is how it treats its women and girls (34)." viewers of CotBW should consider the following ramifications:
Transit reform made clear the economic gap between Communist-East and subsidized Capitalist West Berlin (35).
Women in the GDR were for the first time in decades exposed to wage disparity as economic norms of the west pervaded the GDR (36). Rates of the pay-gap between GDR men and women went from roughly 6% to 25% (37)
Reproductive rights and the right to childcare were essentially revoked from former-East German Women (38).
Hostile idealization from both former east and west german Women served to slow integration while also creating a foundation for Ostalgie (nostalgia for the GDR) as Women had to find alternative social fulfilments beyond work or motherhood (39).
The noun definition of a collapse is "an instance of a structure falling down or in (40)." Therefore given economic collapse prior to reunification of Germany and the elimination of comparatively progressive socialist state-structures, collapse is seemingly the most befitting descriptor.
While collapse is negated by reunification of Germany, which came in 1990, it does not address the questions contemporary people face today.
