"Obama's 'American Opportunity Tax Credit' proposal would provide students up to $4,000 for schooling each year in return for 100 hours of annual community service," the Naples Daily News reports. "Obama's proposal would base the tax credit on the previous year's tax returns, so funds would be available to students and families at the beginning of each school year. The credits would also be fully refundable, allowing low-income families who don't pay enough in taxes to take advantage of the program, as well. Estimates out of the Obama camp peg the yearly cost of the program at $10 billion, which would come from cutting some existing federal programs, reducing funding for others and scaling back on congressional pork-barrel spending."
