Romney's Running for President

From Portfolio.com:

"From my first day in office my No. 1 job will be to see that America once again is No. 1 in job creation," he said as he officially announced his candidacy in New Hampshire, home of the 2012 campaign’s first presidential primary.

Does anyone know when the last year that the U.S. led the world in job creation?  I would guess late 90's at the most recent, if even then.  I would like to know how Romney will create more jobs in the U.S. than will be created in China.  Maybe by lowering U.S. wages to Chinese rates?

Update:  Better late than never, I changed the text color of the quote to make it more readable.  Sorry, I've been busy trying to get the crops in.
