Ideology keeps them from governing effectively

NYT:

With a strong directive from the Bush administration, Congress set out more than a year ago to fashion legislation that would protect America's private pension system, tightening the rules to make sure companies set aside enough money to make good on their promises to employees.
Then the political horse-trading began, with lawmakers, companies and lobbyists, representing everything from big Wall Street firms to tiny rural electric cooperatives, weighing in on the particulars of the Bush administration's blueprint.
In the end, lawmakers modified many of the proposed rules, allowing companies more time to cover pension shortfalls, to make more forgiving estimates about how much they will owe workers in the future, and even sometimes to assume that their workers will die younger than the rest of the population.
On top of those changes, companies also persuaded lawmakers to add dozens of specific measures, including a multibillion-dollar escape clause for the nation's airlines and a special exemption for the makers of Smithfield Farms hams.
As a result, the bill now being completed in a House-Senate conference committee, rather than strengthening the pension system, would actually weaken it, according to a little-noticed analysis by the government's pension agency. The agency's report projects that the House and Senate bills would lower corporate contributions to the already underfinanced pension system by $140 billion to $160 billion in the next three years.

It never ends, as long as the lunatics rule us.
