It's probably some math involving "unfunded liabilities" that the government has (usually oversized pensions or something).
This can cause a cascade where the governmental entity that has the liabilities keeps raising taxes on its constituents so they keep moving outward to the suburbs or away.
Detroit is a famous example of this, but it's happened to other areas (cities have gone bankrupt before).
