That's not how quantitative easing works. Quantitative easing doesn't fire up the printing presses. Bernanke can add $2 trillion into the system within 15 minutes, and no paper money is printed or manpower expensed aside from a few clicks on a computer mouse. Once you secure your financial system network, adding currency adds virtually no costs relative to the amount of currency you put into that system. You've already secured the network.

It's akin to Facebook's security system. It works the same regardless if it's 100 million users or 1 billion users.
