Textbooks don't teach people how to avoid paying any income tax. But that's what an army of tax lawyers and corporate tax accountants do.

For many people, the mortgages they took out before 2008 are so high that they would be better off walking away from their houses. That is called "jingle mail," returning the keys to the bank and saying, "You can have the house. I can buy the house next door that's just like this for 20% less, so I'm going to save money and switch." That's what someone like Donald Trump or a real estate investor would do. But the banks are trying to convince the mortgage debtors, the homeowners, not to act in their own self-interest.

Paying debt service to banks leaves less income to buy goods and services.

The real estate interests and banks are in a kind of symbiosis. They're the largest-growing part of the economy. This is the sector that backs the political campaigns of senators, presidents and congressmen, and they use this leverage to make sure that their people dominate the Federal Reserve, Treasury and the federal housing agencies.

One of the big problems in America's economic polarization and shrinkage is that pensions can't be paid. So there are going to be defaults on pensions here, just like Europeans are insisting in rolling back pensions. You can look at Greece and Argentina as the future of America.

The effect of metals speculation was to push up the prices that China had to pay to countries like Australia. This squeezed China. Once the speculative demand ended, all of a sudden the added production facilities that had been brought into production by the high prices went out of production again, and there was a glut.

In order to be an economist these days, you have to participate in this fairytale that somehow we can recover and still make the banks rich. And it is a fairytale.
