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.

Mr. Trump wants to turn the U.S. economy into the kind of real estate development that has made him so rich in New York. It will make his fellow developers rich, and it will make the banks that finance this infrastructure rich, but the people are going to have to pay for it in a much higher cost for transportation, much higher cost for all the infrastructure that he’s proposing. You could call Trump's plan "public investment to create private profit". That's really his plan in a summary.

The current U.S. and Eurozone depression isn't because of China. It's because of domestic debt deflation. Commodity prices and consumer spending are falling, mainly because consumers have to pay most of their wages to the FIRE sector for rent or mortgage payments, student loans, bank and credit card debt, plus over 15 percent FICA wage withholding for Social Security and Medicare actually, to enable the government to cut taxes on the higher income brackets, as well income and sales taxes.

So the Bush-Obama administration has taken a fiscal stance diametrically opposed to that of the patron saint of free enterprise. While escalating war in Afghanistan and maintaining over 850 military bases around the world, the administration has run up the national debt that Smith decried. By shifting the tax burden off property and off rent-seeking monopolies - above all, off the financial sector - this policy has raised America's cost of living and doing business, thereby undercutting its competitive power and running up larger and larger foreign debt.

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.

Debt deflation is when there's less money that people have to spend out of their paychecks on goods and services, because they're paying the FIRE sector. Oil going down is a function of the supply and demand of oil in the market. It's a separate phenomenon.

When you buy enough stocks to give you control of a target company, that's called mergers and acquisitions or corporate raiding. Hedge funds have been doing this, as well as corporate financial managers. With borrowed money you can take over or raid a foreign company too. So, you're having a monopolistic consolidation process that's pushed up the market, because in order to buy a company or arrange a merger, you have to offer more than the going stock-market price. You have to convince existing holders of a stock to sell out to you by paying them more than they'd otherwise get.
