We're living in a world that's divided into two economies: the economy of the 1%, and the economy of the bottom 99%. I guess you could be more "centrist" and say the top 10% versus the bottom 90%. But there's definitely a stratification at work here.

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.

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.

The United States is pushing as policy division of the world into rival currency camps - the dollar area on the one hand, and the Russia-Chinese-Shanghai Cooperation Organization group on the other, especially now that the IMF has changed its rules. People think that if there are rival currency groupings and national currencies are going bust, we might as well use gold as a safe haven.

There are two definitions of deflation. Most people think of it simply as prices going down. But debt deflation is what happens when people have to spend more and more of their income to carry the debts that they've run up - to pay their mortgage debt, to pay the credit card debt, to pay student loans.

The fact that you have government-guaranteed student loans has created a whole new sector in the American economy that didn't really exist before - private for-profit universities that sell junk degrees that don't help the students. They promise the students, "We'll help you get a better job. We'll arrange a loan so that you don't have to pay a penny for this education." Their pet bank gets them the government-guaranteed loan, and the student may get the junk degree, but doesn't get a job, so they don't pay the loan.

Most of the European leaders look at themselves as having to follow the United States, because if the US opposes them, there will be a regime change.
