Bush's Pension Relief plan that was signed into effect a few weeks ago is definitely a step in the wrong direction.  Oligopoly Watch has a pretty good analysis of the situation.

The entry also points to the Heritage Foundation which say on its website:

By allowing companies to avoid funding their pension plans' deficits, the new law makes it likely that taxpayers will have to pick up that liability. The sad fact is that many companies that qualify for the funding holiday will be in equally poor financial shape in 2006. The delay is likely to cause these plans to accrue even higher funding deficits. Moreover, once the companies submit their even more underfunded plans to PBGC, that agency will be further down the road toward an inevitable taxpayer-funded, multibillion-dollar bailout.
