Borrow and Spend Conservatives
Borrow and spend conservatives: An intentionally assymetrical contrast to the original term "tax and spend liberal." Intended as a derogatory term, denoting hypocrisy among those who proffer themselves as financial conservatives.
These are also known as "credit card Republicans."
Another version of this is "borrow and spend cannibals" which parallels the original and describes the eventual self-consuming result of the policy.
