Will Obama boost US economy?

I happen to hear Obama's acceptence speech ,It was fiery ,inspiring (if i am an American).He is promising a lot ,Pull out army from Iraq ,stop outsourceing ,bring jobs back to America and turn it into a land of oppurtunities again .
But can he do all this if he is elected i doubt .....
anyways he is a leader ,Unlike Mc cain he is all over the media .And let me come to the thing which may affect me ,outsourcing or rather stopping it ,as an indian i am bit concerned about this but there people will always find ways around that .
