““Reciprocal altruism, meanwhile, is rampant in Washington and is the primary channel through which interest groups have succeeded in corrupting government. As the legal scholar Lawrence Lessig points out, interest groups are able to influence members of Congress legally simply by making donations and waiting for unspecified return favors. And sometimes, the legislator is the one initiating the gift exchange, favoring an interest group in the expectation that he will get some sort of benefit from it after leaving office.””
