Unemployment benefits will run out for millions of American workers now that Congress failed to pass an extension for another year. The Labor Department estimates that 635,000 people could lose all benefits by December 11th with more than 1.6 million losing them by Christmas. The Unemployment Bill, along with an extension of the Bush tax cuts, is among the hottest issues in the lame duck session of Congress that started on Monday. Extending unemployment benefits would have cost the country another $12 billion. The tax cut extension could cost $3.7 trillion over the next decade.
