If you have to pay about forty to forty-three percent of your income for housing, you also have to pay fifteen percent of your paycheck for the FICA for Social Security wage withholding. You have to pay medical care, you have to pay the banks for your credit card debt, student loans. Then you only have about twenty-five or thirty-five percent, maybe one-third of your salary to buy goods and services. That's all.

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.

When you say "bank," a bank is a building, a set of computers and chairs and things. The bankers are the people running these banks. They're the chief officers, and they push the loans because they don't care if they go bad. For one thing, they may package these bad loans and sell them off to gullible institutional investors.

Almost all of the demand for oil that suddenly pushed prices up was speculative demand. People began to speculate not only in stocks and bonds and real estate, but also in commodities. The market went up for old tankers, which were used simply to store oil in. A lot of the oil was simply being stored for trading, not used.

Actually, high housing prices don't help the economy. They raise the cost of living.

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.

I think we're in the take-the-money-and-run stage of the economy. So the banks may go under, but the bankers, who make the policy, clean up.
