I guess for me, the fact that the political reality makes infrastructure "hard" is profoundly obvious... And, while the specific details may change with the city, that reality is quite common throughout the US (even the relatively specific economic conditions discussed earlier in the context of Pittsburgh are not really that unique)...

Pretending like this type of infrastructure decline is somehow unique to Pittsburgh, which, at least implicitly, the top level comment does, does a great disservice to actually finding solutions to the problems with that "political reality on the ground" - and not just in Pittsburgh.
