Todd Zywicki, one of my favorite economists, has written a damning indictment of Congress. It makes me squirm.
One interesting aspect of the recent government bailouts has been the complete irrelevance of Congress. The operation and decision-making seems to be run almost entirely by the Secretary of Treasury and Federal Reserve. Congress appears to lack the ability, the will, and the decisiveness to play any role except spectator, as a handful of senior executive branch officials have nationalized major portions of Wall Street.
What is further interesting is that Congress is not missed in the slightest. No one is clamoring for a greater role for our elected representatives in dealing with these problems. I haven't heard anyone saying, "We really need to get Congress more involved in this. They'll know what to do." ...
Put more generally, Congress's ridiculousness has increasingly caused it to forfeit its status a co-equal branch of government. 40 or 50 years ago it might have been plausible to imagine Congress addressing important public policy issues like entitlement reform or health care reform (I'm not saying they would have done it, but it seems like it was more plausible then). Serious people were in the Senate then--Taft, Johnson, etc. Today, however, the idea that serious solutions to pressing social problems might originate in Congress is hard to suggest with a straight face.
Also fascinating: the People know that Congress is useless... that's why the branch's approval ratings are in the single digits. Zywicki doesn't suggest a way to fix it, but I think a good place to start would be to repeal the 17th Amendment.
