When people are running up more and more debt for housing, they call that "real wealth." It exposes what's wrong in the mainstream economics and why most of the economics that justifies austerity programs and economic shrinkage is in the textbooks is not scientific. Junk economics denies the role of debt and denies the fact that the economic system we have now is dysfunctional.

The ideological foundation of today's business schools is that economic control should be shifted out of government hands into those of financial managers - that is, Wall Street.

From 2008 to 2016 all the growth in the American economy, all the growth in national income, was earned just by the wealthiest 5% of the population. So they got all the growth. 95% of the population didn't grow. If you can get a flat tax or other lower tax, as Trump is suggesting, then this richest 5% will be able to keep even more money. That means that the 95% will be even poorer than they were before, relative to the very top.

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.

A derivative is a bet on whether a stock, or a bond or a real estate asset, is going to go up or down. There's a winner and a loser. It's like betting on a horserace.

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 United States Government has fought against creation of an international court to adjudicate the ability of national economies to pay debts.
