THE human side of the recession, in the new media genre that’s been called “recession porn,” is the story of an incremental descent from excess to frugality, from ease to austerity. The super-rich give up their personal jets; the upper middle class cut back on private Pilates classes; the merely middle class forgo vacations and evenings at Applebee’s.

But the outlook is not so cozy when we look at the effects of the recession on a group generally omitted from all the vivid narratives of downward mobility — the already poor, the estimated 20 percent to 30 percent of the population who struggle to get by in the best of times.

This spring, I tracked down a couple of the people I had met while working on my 2001 book, “Nickel and Dimed,” in which I worked in low-wage jobs like waitressing and housecleaning, and I found them no more gripped by the recession than by “American Idol”; things were pretty much “same old.”
