Philadelphia losing class

The working class -- what did you think I meant::

The creative class -- workers in science, technology, business, management, arts, culture, media, entertainment, healthcare and law -- makes up 34.6 percent of the metro area's workforce. And the service class -- workers in food service, retail sales and clerical/administrative positions -- makes up 47.5 percent.

That leaves the working class -- those employed in factory jobs, transportation and construction -- as just 17.8 percent of the region's workforce.

"This is startling in a city that was an early manufacturing powerhouse, a center for ship-building, railroad manufacturing and pharmaceuticals, not to mention manufacturing capabilities in beer, candy, and even brooms," Atlantic Cities co-founder Richard Florida writes.

So many of the urban pathologies that we talk about here in Philly, day after day after day, stem from this simple fact -- entire neighborhoods built up around factories that vanished decades ago. But it's a simple fact that is so rarely even brought up.
