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.

Every government, from the Obama administration right through to Angela Merkel, the Eurozone and the IMF, promise to save the banks, not the economy.

The problem is indeed that one party's debt finds its counterpart in some other party's savings. Not paying debts therefore involves annulling some other party's financial claims on the debtor.

Oil is a special case. Saudi Arabia is trying to drive U.S. fracking rivals out of business, while also hurting Russia. This lowers gas prices for U.S. and Eurozone consumers, but not by enough to spur economic recovery.

If you want to see where Trump is moving, look at what the United States neoliberals advised Russia to do after 1991, when they promised to create an ideal economy. Russia was under the impression that the neoliberal advisors were going to make Russia as rich as the United States. What they really did was create a kleptocracy that was virtually tax-free.

Since 2008 you've had the largest bond market rally in history, as the Federal Reserve flooded the economy with quantitative easing to drive down interest rates. Driving down the interest rates creates a boom in the stock market, and also the real estate market. The resulting capital gains not treated as income.

Debtor countries may postpone the inevitable by borrowing from the IMF or U.S. Treasury to buy out bondholders. This saves the latter from taking a loss - leaving the debtor country with debts that are even harder to annul, because they are to foreign governments and international institutions.
