I think the legislation may change spending, but they will still spend. The banks have too much self interest involved to allow that side of their business to go away. Credit card business is very profitable even if there are defaults. As with everything, it just depends on how many defaults. The mortgage "crisis" is the same way. People got into trouble because of two things: (1) When the IRS dropped the interest deduction on consumer debt, the borrowing shifted to borrowing against folk's homes. If you borrowed too much, and with home values dropping in many markets, eventually there is nothing left to borrow or you are upside down on the loans. (2) People bought homes they could not afford due to lax loan practice encouraged by the government buying with adjustable rate loans at low interest rates or buying based on some introductory interest rate. You throw in the drop in home values, rising unemployment, banks becoming less flexible about loan terms, you have the basis for a building problem.
