People will not ship or produce if the cost to produce+ship is higher than what they can recoup. There is a bottom on prices despite what the idiotic supply and demand curves in textbooks show. Contrary to what they tell you in economics 101 supply and demand is not a law, there are significant exceptions.
In fact, if the price of shipping increases enough to make production uneconomic, then people will be laid off. When this is occurring throughout the world, you get a ripple effect. It’s not self-reinforcing in the sense that it increases the price of oil (in fact, it decreases it), it is self-reinforcing in the sense that it does make the economy worse, because it reduces demand for a wide variety of goods, whether shipped or not.
What happens then is what we’ve seen before, the price of oil drops and you get a “recovery”, which is to say a pendulum from shitty economy to sucky economy and back again. The current economic juggling act is about making sure the economy stays sucky, and doesn’t get to shitty, and you do that by keeping the price of oil from exploding. When it does, you lose.
There can be no good global economy right now. There is not enough oil in the world to do it under current economic models. Cannot be done. You may be able to have a few places doing well, but only a few. The solution to this is to GET OFF OIL, but no one is willing to allow that to happen, because old money wants to control the new economy and isn’t sure they can do that with current technologies. That’s why you have idiots talking about shale oil, or using natural gas, or anything else which keeps an economy where a small group of people provide the energy for everyone else, and make a killing doing so.
So instead you have revolutions, you have unions being crushed and so on. At its base this is all related to the price of oil. Oil in Saudi Arabia costs about $7/barrel to produce. Think about what that means in terms of profit, especially in a country where those profits stick to the hands of a few people. Think about the fact that with all that money they could buy anything, unless the US has rich as rich as Saudi Princes and companies which are so large in terms of market capitalization that they can’t be bought. (Well, or they could do ownership controls, but strangely, they prefer to be stinking rich.)
The rich MUST be kept rich. If they aren’t, the oilarchies buy up everything. That’s not exactly true, but it is true enough because that’s the way the people at the top think. They know that they either stay so big they can’t be bought, or they’re bought.
Of course there’s more to this. We could discuss regulatory and environmental (and labor, but labor is the smallest part of it) arbitrage to China (who refuse to allow outsiders to buy anything that matters, period.) We could talk about the structure of the suburban economy, which is both profoundly unproductive and based on oil, so that any nation which embraces suburbanism can’t boom without driving up oil prices and, at this point, causing oil price spikes. We could talk about financialization, but financialization is just a side-effect of needing lots of rich people and having less and less to sell to the world, which is about suburbanization, which is what the rich bribed the middle class with – you can have your little castle and your unearned unwarranted wealth increase in your unproductive suburb away from brown and black people, in exchange we get to be really, really rich. Like all deals with the devil, of course, most people get cheated, but then when you decide you deserve money you didn’t earn and that being away from black people is important to you, you’ve already sold your soul. The rich will find this out as well.
