You want to talk about how to cut expenses, raise revenue, or both to reduce the debt fine but that's a seperate dicussion from the debt-ceiling.

The debt ceiling pertains to spending already incurred--paying your credit card bill in a sense--and it should go without saying that not paying your liabilities results in a default.

Unless the party in power wants the U.S. to default, of course they're going to increase the debt-ceiling.
