This becomes a case of 'who judges he judges' Congress is SO CURRUPTED by pork barrels, it CAN NOT be counted to represent the welfare of the people who elected them, but the money filth who bribe them.

Pork barrel projects
It's short for "pork barrel spending." A pork project is something paid for by federal dollars that only benefits a limited number of citizens, and that the greater majority of the citizens sees as unnecessary.
Typically, 'pork' involves funding for government programs whose economic or service benefits are concentrated in a particular area but whose costs are spread among all taxpayers. Public works projects, certain national defense spending projects, and agricultural subsidies are the most commonly cited examples. Pork is often identified as a key cause of government waste in the United States, specifically by funding programs which were not requested, authorised, competitively awarded, exceeding the budget, not subject to congressional hearings, and/or only serve a local, special interest.
In politics, the biggest disadvantage is that it leads to bargaining for projects to be done and leads to wasteful and irresponsible spending.
