The president added that the ongoing economic recovery and the nation's prosperity in the future depend on the success of America's small businesses and entrepreneurs. "Small businesses are the heart of the American economy," he said, noting they account for half of all private sector jobs. His stimulus plan raises the guarantees on Small Business Administration loans to 90 percent and eliminates costly fees for borrowers and lenders. The plan also includes a series of tax cuts for small businesses and tax incentives to encourage investments in small businesses. Meanwhile, the Treasury Department has launched the Consumer and Business Lending Initiative to help unfreeze the credit markets, Obama said. "We've already done a lot. But we've got to do more," he said.
