You're having government spending on the economy being cut almost everywhere. That means that the only source of spending for growth has to come from borrowing from the banking system.

Every government, from the Obama administration right through to Angela Merkel, the Eurozone and the IMF, promise to save the banks, not the economy.

Nothing could be better for the economy than to get rid of fracking.

The vast majority of $100 bills are abroad, not in the United States. So yes, of course there's a use here but nowhere near as much as there's a use for $100 bills abroad.

Economists often define their discipline as "the allocation of scarce resources among competing ends." But when resources or money really become scarce, economists call it a crisis and say that it's a question for politicians, not their own department.

Mathematically, debts grow exponentially at compound interest. Banks recycle the interest into new loans, so debts grow exponentially, faster than the economy can afford to pay.

This is not really currency that circulates. It's like the old joke about expensive vintage wine. Wine prices will go up and once in a while somebody will buy a 50-year-old bottle of wine and say, "Wait a minute. This has gone bad." The answer is, "Well, that wine isn't for drinking; that's for trading." These $100 bills aren't meant to circulate. They're not to spend on goods and services. They're a store of value. They're a form of saving.
