The problems of 2008 were never cured. The Federal Reserve's solution to the crisis was to lend the economy enough money to borrow its way out of debt. It thought that if it could subsidize banks lending homeowners enough money to buy houses from people who are defaulting, then the bank balance sheets would end up okay.

Economists often define their discipline as "the allocation of scarce resources among competing ends." But when resources or money really become scarce, economists call it a crisis and say that it's a question for politicians, not their own department.

The one sure mark of a con, though, is the promise of free money.

In real estate you can avoid ever having to pay a capital gains tax, decade after decade, century after century. When you sell a property and make a capital gain, you simply turn around and buy a new property. The gain is not taxed. It's called "preserving your capital investment" - which goes up and up in value with each transaction.

The banks' product is debt. They try to tell customers that "debts are good for you," but the customers can't afford any more debt, so there's no way the banks can continue their current business plan.

Trump's claims that he's making taxes more democratic for the people, but it actually is a vast sucking of income and wealth upward.

People think of a parasite as simply taking money, taking blood out of a host or taking money out of the economy. But in nature it's much more complicated. The parasite can't simply come in and take something. First of all, it needs to numb the host. It has an enzyme so that the host doesn't realize the parasite's there. And then the parasites have another enzyme that takes over the host's brain. It makes the host imagine that the parasite is part of its own body, actually part of itself and hence to be protected. That’s basically what Wall Street has done.
