Because the PRODUCERS still outpace the NON-PRODUCERS in your examples. In Detroit the MATH caught up with them a long time ago as the NON-PRODUCERS segment of their communities overwhelmed a continually diminishing group of PRODUCERS.
With contracting economies the MATH can catch up with the regional economic situation real fast. Two major components that CIA analysts track as they predict instability in a region is the PRODUCERS to NON-PRODUCERS ratio, as well as the TOP 10% of wealth from the BOTTOM 10% of wealth distance (Top 10% over 18 times greater in wealth than the bottom 10% is usually the threshold for social rioting and unstable governemnt existence).
As the US government forces more financial burden on the diminishing PRODUCERS in society, they push the US closer to MATH that can't be supported by the historical realities of human history.
