There is no definite answer to the economy problems. In addition the US is only one of many nations which are being affected by the crisis, so it is debateable that even the actions of the president if the USA would change things for the better.
I, as you can tell by my name, would simply spread the wealth around and just create a total classless society in which the people control all property and their own economy. And I would have special vanguards wo lead the people to a virtus and peiceful life. I would also keep the Army away from becoming a conscript issue unless there was a seriouse problem with national existance.
Then I would set up a socialist republic to ensure that totalitarianism, the very object of communism's demise, never happen, This would also help ensure there are less corrupt politians per people in the government because it is a group of people working togather to ensure that there are no greedy people ruining the system.
And when I die, hopfully there would be no need for a government or a sociaty of classes.
