Since June 1, when federal unemployment benefits began to expire, an estimated 325,000 jobless workers have been cut off. That number will swell to 1.25 million by the end of the month unless Congress extends the benefits. The Senate, so far, has failed to act.

Some senators, including Democrats, have balked at an unrelated provision that would begin to close a tax loophole enjoyed by some of the richest Americans. You heard right. Desperately needed unemployment benefits have been held hostage to a tax break for the rich, and the Senate’s Democratic leadership has had to delay and finagle to get its own caucus in line.

State-provided unemployment benefits generally last for 26 weeks, and the federal government picks up the tab after that, provided Congress approves the extensions. There is no disagreement over the need: 46 percent of the nation’s 15 million jobless workers have been unemployed for more than six months  a higher level than at any time since the government began keeping track in 1948.

There is not even any genuine debate about how to pay for extended benefits. An extension through November would cost about $40 billion. But unemployment benefits are correctly considered emergency spending  they are a vital safety net, and the money is crucial to supporting consumer demand in a weak economy  and exempt from pay-as-you-go budget rules.
