I don't think that governments should permit speculation in raw materials, because they're what the economy basically needs.

In fact, there's no way that banks can be paid everything that they're owed.

The result of this anti-classical revolution you had just before World War I was that today, almost all the economic growth in the last decade has gone to the One Percent. It's gone to Wall Street, to real estate.

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 other dynamic keeping the stock market up - both for technology stocks and others - is that companies are using a lot of their income for stock buybacks and to pay out higher dividends, not make new investment,. So to the extent that companies use financial engineering rather than industrial engineering to increase the price of their stock you're going to have a bubble. But it's not considered a bubble, because the government is behind it, and it hasn't burst yet.

People tend to think that paying a debt is like going out and buying a car, buying more food or buying more clothes. But it really isn't. When you pay a debt to the bank, the banks use this money to lend out to somebody else or to yourself. The interest charges to carry this debt go up and up as debt grows.

Small banks that lend to consumers are fine.
