America seems to be on a downward slide. Our government spends too much; our economy creates too little; and we aren't preparing our children to compete in a global marketplace. Yet our politicians - Republican and Democrat alike - just don't get it. While once-great cities fall into decay, Washington thrives, living off the hard work and tax dollars of the private sector. It's time for an American comeback -- and it starts with innovation.   Throughout its history, America's great innovators have been the drivers of our unsurpassed economic success. American innovation transformed a country of ragtag farmers into the epicenter of the world's technological progress. Innovation creates jobs, markets, and new industries where none existed before.
