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.

That's the "magic" of double-taxation treaties: you can shop around for the lowest taxer.

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.

People tend to think that paying a debt is like going out and buying a car, buying more food or buying more clothes. But it really isn't.

To save the banks, you would have to turn the entire Eurozone into Greece.

The IMF acts as the collection agent for global bondholders. Its projections begin by assuming that all debts can be paid, if economies will cut wages and wiping out pension funds so as to pay banks and bondholders.
