What do the 5%, or the 1% actually use their money for? They lend it back to the economy at large, they load it down with debt. They make their money by lending to the bottom 95%, or the bottom 99%. When you give them more after-tax income, it enables them to buy even more control of government, even more control of election campaigns. They're not going to spend this money back into the goods-and-services economy.

If you increase living standards, you make labor more productive. This is why Asia today is becoming more productive than the United States.

The worst loophole is what Donald Trump has talked about: the tax deductibility of interest. If you let real estate owners or corporate raiders borrow the money to buy a property or company, and then pay interest to the bondholders, you'll load the company you take over with debt. But you don't have to pay taxes on the profits that you pay out in this way. You can deduct the interest from your tax liability.

When Mr.Trump says he wants to help all Americans, he means he wants to help all Americans in the 1% by really letting Wall Street get a huge debt from the 99% of the Americans. It's just the opposite of what people believe.

One of the big problems in America's economic polarization and shrinkage is that pensions can't be paid. So there are going to be defaults on pensions here, just like Europeans are insisting in rolling back pensions. You can look at Greece and Argentina as the future of America.

Europe is sort of like the Soviet Union in the '30s and '40s. There was an argument, is it reformable or not? There is a feeling, and I think it's correct, that the European Union, the eurozone, and the euro, is not reformable, as a result of the Lisbon treaties and the other treaties that have created the euro. Europe has to be taken apart in order to be put together not on a right-wing, neoliberal basis, but on a more social basis.

So the political choice today is much like the 1930s, when the global economy also broke down. The choice is between nationalism and populism on the right, or socialism reviving what used to be left-wing politics.
