Barely surviving on credit cards

These days, more and more people are saying "Charge it."

Finding themselves strapped for cash and unable to use their home as an ATM, Americans are increasingly turning to credit cards to cover gas, groceries and other living expenses.

But many find themselves struggling to pay the burgeoning bills at a time when even the basic needs are growing costlier.

For many people, racking up credit card debt is not a choice they want to make, experts say. Not too long ago, they could have tapped into the equity in their homes through loans or lines of credit or refinancing. But this debt, which usually carries lower interest rates, is no longer as widely available with the collapse of the housing market.

So, faced with soaring costs for food and fuel, people find they must charge more to make ends meet.
