Reads like an article from The Onion, but he is actually completely correct:
"it must be understood that there is simply no such thing as the U.S. Federal government running out of money, nor is the Federal government operationally dependent on borrowing from China or anyone else. U.S. states, individuals, and companies can indeed become insolvent, but U.S. government checks will never bounce,” states Mosler. “Yes, large Federal deficits that push the economy beyond the point of full employment can lead to inflation or currency devaluation, but not bankruptcy and not bounced checks."
