Well, all big businesses are international businesses, so that goes without saying. Also, small businesses are growing substantially, and have been for the past decade or so, both under Clinton and under Bush.
what he has failed to do is ... make us products more competitive abroad.
Since when is he supposed to do that? Also, while it is true that American businesses have been losing their competitive edge on traditional products, they are, at the same time, unsurpassed when it comes to innovative technological advances. I would point you to two companies which have profited immensely under Bush - Google and Apple. In the process, hundreds of their American employees have become millionaires, and thousands of their shareholders here have reaped enormous wealth. Would you give Bush credit for Google (went public in 2004) and Apple (skyrocketed after iPOD launch last year)?
Microsoft has over 1200 openings right now, most in the Redmond, WA area. That is another innovative American company prospering, and in the process, enriching Americans. Would you give Bush credit for that also?
