Other rent-seeking groups are dispersed across the political spectrum. The tax code has been tweaked 4,428 times in the past 10 years, to the benefit of interests of left, right and center.

Others exercise their power transparently and democratically. As Will notes, in 2009, the net worth of households headed by senior citizens was 47 times the net worth of households led by people under 35. Yet seniors use their voting power to protect programs that redistribute even more money from the young to the old and affluent.

You would think that liberals would have a special incentive to root out rent-seeking. Yet this has not been a major priority. There is no Steve Jobs figure in American liberalism insisting that the designers keep government simple, elegant and user-friendly. Sailors scrub their ships. Farmers clear weeds. Democrats have not spent a lot of time scraping barnacles off the state.

Worse, in an attempt to match Republican rhetoric, Democratic politicians are perpetually soiling the name of government for the sake of short-term gain. How many times have you heard Democrats from Carter to Obama running against Washington, accusing it of being insular, shortsighted, corrupt and petty? If the surgeon himself thinks his tools are rancid, why shouldn’t you?

In the past few weeks, the Obama administration has begun his presidential campaign by picking a series of small fights with the Republican-led House over things like recess appointments. These vicious squabbles may help Obama in the short term by making him look better than Republicans in Congress. But they will only further discredit Washington over the long run.

Life is unfair. Republican venality unintentionally reinforces the conservative argument that government is corrupt. Democratic venality undermines the Democratic argument that Washington can be trusted to do good.
