Companies are alarmed at potentially costly provisions in the Senate healthcare bill, many of which they hope will be scrapped during a final round of negotiations early next year. A scramble to massage the hefty measure, instead of pushing to kill it, reflects the view of many in the business community that a sweeping remake of the healthcare system now appears inevitable. The U.S. Chamber of Commerce is among a few big business groups calling for Congress to scrap the overhaul effort. Business is worried that President Barack Obama's push to extend coverage to millions more Americans will raise the burden on employers. Business groups have widely criticized the 2,074-page Senate bill, which looks set for passage on Christmas Eve. They also have offered a variety of fixes.
