@contrex,
Quote:So I revise my earlier post. A wall is a substantial barrier, not easily removed, unlike (say) a fence. The "walls" were substantial accumulations of savings in the East and debts in the West which were so large that they formed barriers which restricted the possible actions that could be taken to overcome the 2008 economic crisis. Countries were hemmed in by these walls.
To me, the issue is this: one of the problems that lay behind the 2008 crisis was the fact that we had a wall of saving, a wall of money, in the east and a wall of debt in the west. This imbalance of money, this massive surplus of cash seeking out places to invest, led to all the problems of new bonds and financial instruments being created and the asset bubbles in the west that, when they burst, caused so much damage.
East - tons of money, a huge wall of money looking for a place to earn interest
West - tons of debt, a huge wall of debt, a self standing, unsupported, shaky wall. Shady bankers and other financial gurus created dodgy new investment schemes which caused folks to think that there was really a boom going on, one that had a foundation. This created asset bubbles in housing, ....
Similar uses of 'wall' meaning something large and unstable.
Wall of death - from an avalanche, tsunami, rock slide, mud slide, ...
When the bubble, which was just a barely legal Ponzi scheme, burst, ... the resultant mess.
The walls, to my mind, refer to humongous amounts of hard cash [east] and humongous debt [west]. Both were unstable.
