Not sure about that. Bush still has a lot of power to nullify unfair trade agreements like NAFTA, and to end the H1-B and L-1 visas, as well as tax companies that outsource, give tax breaks to companies that open factories that employ americans, shift away from depending on a personal income and instead finance our government with tarrifs like we used to.
What you seem to forget, is that bush is the leader of the republican party, who control both housed of congress. Just about anything that bush wanted to do to improve the jobs and economy, would sail thru congress , but they arent even proposing to do anything, much like Hoover ignored the economy.
