Once in a while I get back in touch with reality by having a look at the Fortune 500 list.
What you find is what you think is big, is usually measured by what is loud. Microsoft, Apple, Google, and all the other tech companies. Even the media fall for this one, because they report on future potential business growth which is more newsworthy than stark reality.
Go play with the Forbes Global 2000 list, and tell me if you can see a pattern. Sort by Revenue. Sort by Market Value. And then sort by Profit!! The Profit one will have you fall off your seat! Those are the bastards that are ripping us off!! The ones making all the profit!
Yep, the world is dominated by oil. Cars feed off oil. And banks finance all this stuff.
I'd guess that anything that's a threat to the oil/cars/banking combination will be squashed, even if we as consumers or democracies want it a different way. There's too much at stake to let go of all that money.
Just one problem....the oil is running out!! See Peak Oil.
