WASHINGTON - Congress has become the butt of late-night comedians for waiting until the last minute to do any work, yet its procrastination involves something more than fecklessness: The issue over which it keeps stumbling not only separates its two parties into warring camps, but divides them internally.
At its core, the debate over the size of government and how to pay for it pits the interests of the huge baby boom generation, now mostly in their 50s and 60s, against the needs of the even larger cohort in their teens and 20s.
With limited government money to spend, how much should go to paying medical bills for retirees vs. subsidizing college loans, job training and health care for young families with children?
As they grapple with that, the party of small government increasingly relies on the votes of people dependent on entitlement spending. And the party that created the massive government programs for retirees has more and more become the political home of the young.
The part of the debate that ended Tuesday night mostly involved how limited the government's resources would be. Congress agreed to add about $620 billion to federal revenue over the next decade. But the vote locked in place the Bush-era tax cuts for everyone with incomes below $400,000 a year, a decision that denied the Treasury about $4 trillion over the same period.
That vote did not end the tax debate, but it did settle the biggest part of it. White House officials say that this spring, when the next budget deadline arrives, President Obama will seek several hundred billion dollars more over the next 10 years. But even if he prevails over Republican opposition, the increment would be relatively small.
Increasingly, therefore, the coming fights over the budget will focus on the topic that both sides have shied away from: spending on retirees.
