He is admitting they just create it out of thin air (that is the way the Fed works), so no reason they can't create an amount approaching infinitely at a very large number. Of course they really can't create an infinite amount.

But they have no limit apparently . . . And this is what happens when you have an "infinite" amount of cash created out of thin air:

A loaf of bread can cost more than you could take to the store in a wheelbarrow. Get paid daily, run to make transactions on your lunch hour before your pay deflates to nothing.

" In 1914, before World War I, a loaf of bread in Germany cost the equivalent of 13 cents. Two years later it was 19 cents, and by 1919, after the war, that same loaf was 26 cents - doubling the prewar price in five years.

"Bad, yes -- but not alarming. But one year later a German loaf of bread cost $1.20. By mid-1922, it was $3.50. Just six months later, a loaf cost $700, and by the spring of 1923 it was $1,200. As of September, it cost $2 million to buy a loaf of bread. One month later, it cost $670 million, and the month after that $3 billion. Within weeks it was $100 billion, at which point the German mark completely collapsed."
