If you're ambitious and individualistic (as those who create the most economic value are), there's no alternative to the United States still.
If you're from a wealthy place like Europe or Canada: The United States is still far richer, bigger market, and more risk-encouraging than your homeland. Not everybody will want to move from those places, but I've seen first-hand how many ambitious people will. The ambitious culture and opportunity can't be overstated, and the ability to create a better life in a far more efficient country that rewards your efforts.
If you're from a poor place like Latin America: Almost anywhere in the United States is still better quality-of-life, better pay, etc., plenty of reasons to move.
From my sample size, the only people discouraged by this are political agitators who take up valuable spots at our universities, and contribute ~nothing to our economy anyways. Almost every immigrant I know supports these actions.
