Panicky protectionists are predicting some unsavory possibilities for the U.S. economy thanks to emerging foreign economies with newly created wealth to invest.

"All together, the sovereign wealth funds of countries like Abu Dhabi and Kuwait have spent over $30 billion bailing out our financial system, which has raised some troubling questions," CBS correspondent Lesley Stahl said. "Are these mostly undemocratic regimes saving Wall Street or invading it? One fund is of special concern - it's new, highly secretive and the fifth largest in the world."
