High prices can be the result of speculation, and maybe plunging prices can be attributed to the end of speculation, but low prices over time aren't caused by speculation. That's oversupply, mainly by Saudi Arabia flooding the market with low-priced oil to discourage rival oil producers, whether it's Russian oil or American fracking.

More and more money is being extracted from of the production and consumption economy to pay the FIRE sector. That's what causes debt deflation and shrinks markets. If you pay the banks, you have less to spend on goods and services.

We're in a chronic debt-deflation. There's no way we can recover unless you write down the debts. And that's what the IMF basically is implying (and it was explicit regarding Greece), but its not spelling it out, because that's not what can be said in polite company.

In order to be an economist these days, you have to participate in this fairytale that somehow we can recover and still make the banks rich. And it is a fairytale.

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.

Today, people are having to spend so much of their money, to acquire a house and to get an education that they don't have enough to spend on goods and services, except by running into yet more debt on their credit cards and other borrowings.

People have to pay so much money to the banks that they don't have enough money to buy the goods and services they produce. So there's not much new investment, there's not new employment (except minimum-wage "service" jobs), markets are shrinking, and people are defaulting. So many companies can't pay their banks.
