In sheer size, the economic measures announced by President Barack Obama to address "a crisis unlike we've ever known" are remarkable. They amount to the most-expensive plans ever to come through the government in peacetime, rivaling and in many cases dwarfing New Deal spending programs that President Franklin D. Roosevelt famously created to battle the Great Depression. They amount to a political tour-de-force. Yet despite the scope of these remedies, gloom and uncertainty about government's ability to deliver a fix persist. (AP Photo/File)
