What does one have to do with the other? Bailing out banks does not happen so people can still keep spending recklessly, it comes from the belief that letting banks fail will cause major harm to the financial system.
"Financial bailouts of lending institutions by governments, central banks or other institutions can encourage risky lending in the future if those that take the risks come to believe that they will not have to carry the full burden of potential losses."
