When Congress enacted sweeping changes in the way the federal government provides public assistance to the poor more than a decade ago, the goal -- in the words of former President Clinton -- was to "end welfare as we know it."
In many respects, that goal has been achieved. The days when someone could receive welfare checks indefinitely are over and welfare rolls have been cut dramatically. But significant numbers of Americans -- some 36.5 million people in 2006 -- still live below the poverty line, according to the Census Bureau. The Department of Agriculture estimates nearly 11 percent of American households suffer from "food insecurity," meaning they don't have access to enough to eat for at least part of the year.
