The price decline is a result of having to pay debts. That drains income from the circular flow between production and consumption - that is, between what people are paid when they go to work, and the things that they buy.

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.

The biggest industrial sector next to real estate is oil, gas and other mineral resources. They don't report any taxable income, because if you depict yourself as earning a profit, you have to pay a tax on it. So, it's all about what accountants choose to declare as profit.

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.

When you buy enough stocks to give you control of a target company, that's called mergers and acquisitions or corporate raiding. Hedge funds have been doing this, as well as corporate financial managers. With borrowed money you can take over or raid a foreign company too. So, you're having a monopolistic consolidation process that's pushed up the market, because in order to buy a company or arrange a merger, you have to offer more than the going stock-market price. You have to convince existing holders of a stock to sell out to you by paying them more than they'd otherwise get.

This is not really currency that circulates. It's like the old joke about expensive vintage wine. Wine prices will go up and once in a while somebody will buy a 50-year-old bottle of wine and say, "Wait a minute. This has gone bad." The answer is, "Well, that wine isn't for drinking; that's for trading." These $100 bills aren't meant to circulate. They're not to spend on goods and services. They're a store of value. They're a form of saving.

That's why Apple, Microsoft and the big information technology companies have kept so much money registered abroad (although in US dollar accounts with a nominal foreign address's owner). They pretend to make their global income in Ireland. They have an office, which could be simply a postal drop box in Ireland, and claim to make all their money there, not in America.
