Debts grow and grow. And the more they grow, the more they shrink the economy. When you shrink the economy, you shrink the ability to pay the debts, so it's all an illusion that the system can be saved. The question is, how long are people going to be willing to live in this illusion?

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.

What's the best gamble in the world, right now? Its betting that Deutsche Bank stock is going to go down. Short sellers borrowed money from their banks to place bets that Deutsche Bank stock is going to go down. Now, it's wringing its hands and saying, "Oh the speculators are killing us." But it's Deutsche Bank and the other banks that are providing the money to the speculators to bet on credit.

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.

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.

The aim of promoting low down payments is to push prices back up so that fewer houses are going to be in negative equity and fewer people are going to walk away from the mortgages. That will save the from taking a loss on their junk mortgage loans.

The price decline is a result of having to pay debts. That drains income from the circular flow between production and consumption - that is, between what people are paid when they go to work, and the things that they buy.
