The operating assumption of the Ponzi scheme is that the tide will always rise

Micheal Hudson from Counterpunch:

"The recent stock market and real estate bubbles are much like pyramid schemes in the sense that what is bidding up stock and property prices is an exponential inflow of new money from pension plans and mutual funds (for shares) and bank credit (for real estate). Venture capitalists are “cashing out” while corporate managers exercise their stock options.

Suppose that mortgage-packaging companies are honest in their appraisals of current price trends. The real estate bubble is nonetheless speculative and postindustrial. The analogy is found when financial managers endorse government policies that encourage the inflation of price for stocks and bonds, stamps and coins, Rembrandts and modern art by claiming that this creates wealth and hence, by definition, pulls living standards and culture onward and upward.

What is wrong with this picture? For starters, it fails to define value as distinct from price, windfall and capital gains as distinct from earned income. It also neglects the fact that market prices rise and fall, but the debts remain in place. And when debts cannot be paid, savings are wiped out".

"Individuals are getting rich while the economy is polarizing between creditors and debtors, property owners and rent-payers. Unproductive investment occurs when it takes the form of windfall “capital” gains, and when it involves going into debt for real estate, stocks or bonds, or “collectibles.” Unproductive credit occurs when commercial banks make loans that merely finance the purchase of property, companies or financial securities already in place.

Two centuries ago, French followers of Count Henry St. Simon outlined an industrial system that was to be based mainly on equity financing (stocks) rather than debt (bonds and bank loans). Their idea was to make industrial banking a kind of mutual fund, so that claims for payment (and hence, the value of savings) would rise and fall to reflect the economy’s earning power. The industrial banking that developed largely in Germany and central Europe differed from the short-term Anglo-American collateral-based trade credit and mortgage lending. But since World War I, global financial practices have been more extractive than productive.

The consequence has been that debts on the economy-wide level have grown more rapidly than the ability to pay. Instead of reducing this debt overhead by earning their way out of debt, economies have sought to inflate their way out of debt. However, the mode of inflation is not the familiar rise in consumer prices, much less wage inflation. Rather, it is asset-price inflation, emanating largely from the United States. Since the gold-exchange standard gave way to the paper dollar standard in 1971, the U.S. economy has become unique in being able to create credit – and foreign debt – without constraint. The result has been an unparalleled growth in debt relative to income, production and wages. This “debt pollution” has been likened to environmental pollution".

"Governments have replaced industrial growth with purely financial wealth creation in the form of a real estate and stock market bubble. This has turned the economic universe upside-down relative to what the classical writers expected to result from the technological progress unleashed by the Industrial Revolution and its parallel agricultural, commercial and financial revolutions. Property and credit have become costs instead of a benefit, institutional forms of rent- and interest-extracting overhead rather than helpful inputs".
