The AP has a dispiriting story about the economic pressures facing American families who live paycheck to paycheck. (thanks to reader R.K.)

The calculus of living paycheck to paycheck in America is getting harder. What used to last four days might last half that long now. Pay the gas bill, but skip breakfast. Eat less for lunch so the kids can have a healthy dinner.

Across the nation, Americans are increasingly unable to stretch their dollars to the next payday as they juggle higher rent, food and energy bills. It’s starting to affect middle-income working families as well as the poor, and has reached the point of affecting day-to-day calculations of merchants like Wal-Mart Stores Inc., 7-Eleven Inc. and Family Dollar Stores Inc.

Food pantries, which distribute foodstuffs to the needy, are reporting severe shortages and reduced government funding at the very time that they are seeing a surge of new people seeking their help.
