So? Let's say a corrupt mayor makes a deal with a building contractor - you pay me a million dollars and I'll give you all the building contracts. Then it was discovered and the corrupt mayor went to jail. Is there any reason the society has to keep the building contracts part of the deal? I see none.

The only difference in this case is that the corrupt officials that betrayed the public interest in exchange for votes and support of a group of special interests are not in jail yet.
