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.

If bankers can push the loans and make more profits for the bank, they get paid higher bonuses. They often also get stock options. If the bank goes under, they get to keep all of these salaries and options - and the government will bail out the bank. These guys will take their money and run, which is pretty much what they're doing now.

Look at Ukraine. Its currency, the hernia, is plunging. The euro is really in a problem. Greece is problematic as to whether it can pay the IMF, which is threatening not to be part of the troika with the European Central Bank and the European Union making more loans to enable Greece to pay the bondholders and the banks. Britain is having a referendum as to whether to withdraw from the European Union, and it looks more and more like it may do so. So the world's politics are in turmoil.

The problem is indeed that one party's debt finds its counterpart in some other party's savings. Not paying debts therefore involves annulling some other party's financial claims on the debtor.

The concept of productivity in America is income divided by labor. So if you're Goldman Sachs and you pay yourself $20 million a year in salary and bonuses, you're considered to have added $20 million to GDP, and that's enormously productive. So we're talking in a tautology. We're talking with circular reasoning here.

If you end internet neutrality and permit mergers of the big information technology corporations, that's a form of rent seeking. It's part of today's political revolution.

Most of these charges that people pay are economically unnecessary. There's no real cost behind them. There's no real value behind them. So, they're what the classical economist called empty pricing. Prices with no real cost value. What they called rent and fictitious capital. Capital claims on junk mortgage borrowers. The pretense is that all these debts can be paid but it's all fictitious, because everybody knows - at least on Wall Street everybody knows - that many debts can't be paid.
