Earmarks may represent relatively small sums in themselves, but they act as a “gateway drug” to more profligate spending. By giving individual Congressmen the gratification of directing small amounts of taxpayers’ money to their own advantage, it makes it more likely they won’t say no later when major new spending proposals like Obamacare are put up for a vote. An addiction to earmarks also reinforces the Washington assumption that more government spending and intervention is always the answer.
