A task force aimed at preventing Philadelphia from going bankrupt has urged the city’s mayor to figure out how to deal with its almost $6 billion pension deficit. Philadelphia hasn't been or isn't the only region in the country dealing with this issue, though.
Detroit was the poster child of cities running out of money. In 2013, the city filed for bankruptcy after accumulating $18 billion of debt. The pension program was said to account for a sixth of that total.
