There's a concept in most SciFi that breaks governments down into two systems:
Territorial States (USA, England, Japan, etc.) &
Multinationals / Non-Territorial States (Apple, Starbucks, Kohl, Banks, Airlines, etc.)
The non-territorial states wield AS MUCH IF NOT MORE power than most land based governments. Many have as much, if not more, money than territorial states. And UNLIKE terretorial states, they can't "lose". Go ahead. Try to Nuke Microsoft. Where do you do it? You CANNOT destroy a multinational company. It's made up of people, and has offices All Over The Globe. Take out one set of headquarters, and they've got 6 more. And remove one set of leaders, and you've got hundreds more. You can fight a war against nation, because they've got limited geography. You can't fight a war against a multinational. They're NOT bound by geography.
In many ways, Multinationals are like 'the nobility' or 'the princes of christendom'. Governements, rather than controlling them, have to treat them as peers. Instead of armies of soldiers and retainers, they have armies of lawyers and bank accounts (as in, if any major corporation in the US LEFT the US, we'd have major economic collapse... which gives them *a lot* of power & political traction). It's a not so balanced stalemate.
It's an old problem, in a new way, and it's born of the Industrial Revolution.
Occupy Wallstreet is the natural progression from Union Strikes (and quite frankly, any smart government will let it continue, to use it as leverage in their own political dance with corporations). People are protesting CORPORATIONS, in much the same way as people have protested governments -or parts of governments- in the past.
Which is a bizarre, yet totally normal/natural progression/attempt to rebalance power that happens periodically throughout history.
What will happen is pretty simple to predict if you study history. 1 of 2 things: Either the rebellion will be put down, and the corporations will continue to run their businesses unchecked (nobles will continue to rule unchecked) and the balance of power will remain the same until the next rebellion OR "something" fundamental will change. Which will keep people "happy" for awhile (aka everyone -both nobles and peasants, or senators and emperor- will be unhappy, but the rebellion will disperse being less unhappy than before) UNTIL some ingenious person or series of people decide to make use of the new system in a way that makes everyone unhappy again, until enough people are unhappy long enough to rebell again.
Jefferson said 'A little revolution is good from time to time.'
That's just what's going on right now.
NOT a lot will change (revolutions rarely change MUCH), but they shake up the balance of power for a bit, which will allow things to change for awhile.
