When I worked as an analyst for Jupiter Research a decade ago, the editorial philosophy was “data-driven analysis”. But sometimes single stories—one or a few individuals—define a trend. That’s my renewed feeling today meeting Tim in the alley behind our apartment.

I measure San Diego’s economy, and in some respects that of America, by the people who dumpster dive our alley. We moved to the city seven years ago yesterday and were taken aback by the number of people who pull redeemable bottles and cans from recycle and trash bins. But the collectors’ character changed in 2009, following the financial crisis of late 2008. No longer did we see just clearly weather-worn homeless, but paler and better-dressed folks not long laid off from office jobs. Professionals.
