Today, people are having to spend so much of their money, to acquire a house and to get an education that they don't have enough to spend on goods and services, except by running into yet more debt on their credit cards and other borrowings.

To save the banks from making losses that would wipe out their net worth, you'll have to get rid of Social Security. It means that you'll essentially have to abolish government and turn it over to the banking system to run, with an idea that the role of governments is to extract income from the economy to pay to the bondholders and the banks.

That's the problem with the financial sector. Banks and the financial sector live in the short run, not the long run. In principle the government is supposed to make regulations that help the economy over time. But once it's taken over by the financial sector, the government lives in the short run too.

If you're a wealthy heir with a trust fund, and you sell stocks, make your 10% gains since Donald Trump, and then you buy other stocks, you can avoid paying taxes. And if your accountant registers your wealth offshore in a Panamanian fund, like Russian kleptocrats do - and as more and more Americans do - you don't have to pay any tax at all, because it's not American income, it's foreign income in an enclave without an income tax.

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.

Now, suppose that a homeowner puts down only 3% of their own money or 3.5% for the FHA. That means if prices go down by only 3%, the house will be in negative equity and it would pay the homeowner just to walk away and say, "The house now is worth less than the mortgage I owe. I think I'm just going to move out and buy a cheaper house." So it's very risky when you have only a 3% or 3.5% equity for the loan. The bank really isn't left with much cushion as collateral.

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.
