CHRISTOPHER S. RUGABERWASHINGTON (AP) â¿¿ Some reward. Here's the assignment President Barack Obama has won with his re-election: Improve an economy burdened by high unemployment, stagnant pay, a European financial crisis, slowing global growth and U.S. companies still too anxious to expand much. And, oh yes, an economy that risks sinking into another recession if Congress can't reach a budget deal to avert tax increases and deep spending cuts starting in January. Yet the outlook isn't all grim. Signs suggest that the next four years will coincide with a vastly healthier economy than the previous four, which overlapped the Great Recession. Obama has said he would help create jobs by preserving low income tax rates for all except high-income Americans, spending more on public works and giving targeted tax breaks to businesses. He used his victory speech in Chicago to stress that the economy is recovering and promised action in the coming months to reduce the government's budget deficit, overhaul the tax system and reform immigration laws. "We can build on the progress we've made and continue to fight for new jobs and new opportunity and new security for the middle class," Obama said. The jobs picture has already been improving gradually. Employers added a solid 171,000 jobs in October. Hiring was also stronger in August and September than first thought. Cheaper gas and rising home prices have given Americans the confidence to spend slightly more. Retailers, auto dealers and manufacturers have been benefiting. That said, most economists predict the improvement will remain steady but slow. The unemployment rate is 7.9 percent. Obama was re-elected Tuesday night with the highest unemployment rate for any incumbent president since Franklin Roosevelt. Few think the rate will return to a normal level of 6 percent within the next two years. The Federal Reserve expects unemployment to be 7.6 percent or higher throughout 2013.
