One significant error in the video...it speaks to investors going to the Federal Reserve to buy Treasury bills. Unfortunately, that's not quite a true statement. While many of the investors receive the bills by purchasing through the Fed, the debt is issued by and is the responsibility of the U.S. Treasury. Because the Fed is the Treasury's fiscal agent (their bank) the Fed acts to collect bids and distribute the securities. It is the Treasury (a separate entity) that decides how much debt to float, for how long, and which bids to accept. And the how much debt to float is largely a result of the Congress's willingness to spend (large) and tax (not as large).
