Okay, this post is going to spiral around into a big theoretical rant in a paragraph or two. To save you the trouble of reading all of it, you don't need to assume a conspiracy to assert that the people we're pissed at knowingly fucked the system for their own gain. You can quit reading now, unless you want to listen to me ramble.
The very short version here, is "greedy algorithm". It's a buzzphrase, unfortunately, but one that's been bouncing around my head for the last week or so. A lot. It's very difficult for a corporation to take any action but what generates the most profit right now - even if there might be something that's better overall. The situation we've got right now can be pretty accurately described as a lot of people independently deciding to take the optimal short-term strategy, because anything else is risky. After all, if you profit now, you can use that profit to survive later on - but if you take a long view, things may change to make your plan less valuable. The people at the top of the system haven't known any other financial system than the one we have right now, and they got there either purely through birth, or more likely through a combination of birth and playing the system. As Aqizzar has mentioned, the safest bet is always that the status quo will continue*, and these people know this.
EDIT: Very important point I forgot to make. This is important because it makes it very hard for them to think about the collapse of that system as a possibility - actions for which that's a potential consequence tend not to have that counted against them, in the same way that as a teenager many people don't devote a lot of thought to the water bill when they take a shower. It's not something you think of as something you need to worry about, even if you understand on some level that it exists. Examples may need to be adjusted by culture but hopefully what I mean is clear. END EDIT.
You can't sacrifice profits in the short term. If you do, your stockholders or your competition or even your fellow employees will eat you alive. Sure, you'll still get a giant severance package - but as I'm sure we're all aware at this point, survival is not a problem for any of these people. It's not actually much of a consolation to get a big pile of money if you're still being deprived of whatever it is that actually drives you. And in the meantime, the company suffers, somebody changes your plan once you're out (so there was never any benefit), and you're out of a job. It's just not rational to pursue long-term gains.
That's why nobody had to conspire to do this. Nobody has to have a master plan to ruin the middle class or crush the economy. That's just what was optimal, for everybody who got to make decisions, when those decisions were made. They all knew that if everybody did the same, things would go to shit, but I doubt any of them particularly wanted to get rid of the middle class. But they all knew that they couldn't be the ones to do things ethically, and they aren't members of the middle class anyway.
And here's where I start ranting about capitalism as a system, because when you get to the bottom of it, the whole thing is basically economic evolution. What's successful, as defined by making money, is going to perpetuate itself simply by virtue of being successful. No matter what its other consequences may be, it's going to keep on perpetuating itself until it dies, and the economy that depended on it crashes. And that's a problem, because as should be obvious, evolution is a terrible fucking way to run a society, in pretty much any respect. This is what happens when you let it run your economy. More importantly, though, it's going to home in on the nearest maximum and never, ever, ever budge. No matter how much better things might be somewhere just past that next dip in productivity, it's too risky to leave until you're forced to.
And that's ultimately what I think this is about. Government intervention is supposed to curb these problems and keep the economy flowing when it would otherwise jam itself into a clusterfuck, but I am starting to suspect that we've reached a point where that isn't feasible any longer. At least not the way we're currently doing things. I don't want a planned economy - as everyone reading this post who disagrees with me has no doubt already started to type, that's sure to fail. We, as a species, simply don't have the ability to actually do that yet. But a designed economy? We need to move toward that, I think. Not one where some public body dictates production and everybody scrambles to meet it, but one where some public body (or, hell, whatever better form of government you can think of) at least dictates how the system is going to work for each type of production, instead of letting things assemble themselves. The fundamental assumptions of the Invisible Hand aren't true, and I'm not sure they ever were outside of their own tiny, local maximum.
Maybe the system already works more like this than I think. I don't know. Maybe I'm not actually talking about anything even slightly new to the world, or maybe the distinctions I'm trying to draw aren't real and I'm just imagining them based on the words. But I hope not.
*Cleverness, as it regards to this whole spiel, is the ability to tell when the status quo is going to fail.
