I think something like three-quarters of American currency is held abroad, by drug dealers, by tax evaders, Russians and Chinese. Other people think that they want to protect themselves against their own currency going down. When you have 75% of the currency and even more of the high-denomination $100 bills held abroad, you wonder whether these are people we really want to pay. If you get rid of the $100 bills, its foreign holders will be the main losers.

The worst loophole is what Donald Trump has talked about: the tax deductibility of interest. If you let real estate owners or corporate raiders borrow the money to buy a property or company, and then pay interest to the bondholders, you'll load the company you take over with debt. But you don't have to pay taxes on the profits that you pay out in this way. You can deduct the interest from your tax liability.

You have to abolish pension plans. You have to abolish social spending. You have to raise taxes. You have to have at least fifty percent of the European population emigrate, either to Russia or China. You would have to have mass starvation. Very simple. That's the price that the Eurozone thinks is well worth paying.

If a lot of money goes into the stock market, it'll push up prices, making money for stock speculators. Then the insiders can decide that it's time to sell out, and the market will plunge.

Everybody would be better off if they could buy housing for only, let's say, a carrying charge of one-quarter of their income. That used to be the case 50 years ago. Buyers had to save up and make a higher down payment, giving them more equity - perhaps 25 or 30 percent. But today, banks are creating enough credit to bid up housing prices again.

The United States and Europe are in a state of debt deflation, where people and businesses have to pay banks instead of spending their income on goods and services. So markets shrink, sales and profits fall, and the stock market turns down.

The one sure mark of a con, though, is the promise of free money.
