Melissa Boteach: Reimagining our social contract

  Every year, the Bureau of the Census releases its estimate of how many Americans lived below the federal poverty line at a specific point in time during the previous year. For the past several years, the official poverty rate has remained steady at about 15 percent.

  Hearing this statistic, one might conclude that the same 15 percent of Americans remain stuck at the bottom, year in and year out, constituting the nation’s poor. But look beyond the point-in-time data, and you will find an important but rarely discussed fact: It is not the same 15 percent year after year.
