It may be unrealistic, but its what America has to do to be successful. Just like any household, you cannot buy more than you make, and if you do you are in trouble. Similarly, America is in trouble because the population imports more than they export.
Obama should come up way short though. Currently, America is at a price disadvantage with lesser developed countries, and that will not change. Without public healthcare and education, America is at a huge disadvantage to other developed countries. Why would a businessman pay an American $50,000 a year then pay $25,000 in benefits when they can hire a European for $50,000 and let the government pay the benefits?
America has a disadvantage compared to other developed countries and lesser developed countries, and all the while Americans love to spend money they dont have. Its a recipe for disaster that no mere mortal is going to fix any time soon.
