I personally think the next city that could face a major economic collapse is Philadelphia. The city has never recovered from the closing of the Philadelphia Naval Yard, and it doesn’t have the diverse economic base of New York City or the status of vital transportation hub like Chicago to keep the city going.

“I personally think the next city that could face a major economic collapse is Philadelphia.”

I too think Philly will fall to bankruptcy, but not as fast as Chicago.

Reason? S&P recently upgraded Philly's credit rating...

...while Moody's just downgraded Chicago's credit rating.

People that buy munis will move money away from Chicago and to Philly at least in the short term.

For this reason, I think Philly will have an incremental amount of time before it goes belly up like Detroit.
