Of the world's 100 largest economic entities, 51 are now corporations and 49 are countries.
This was as of 2000. It's probably now 60 to 70 out of 100.
Remember that corporations exist for one reason — to maximize profits.
And they are eternal.
When they fully rule the world, I believe we will be able to say, in primitive evangelical fundamentalist speak, that ANTICHRIST is ruling. Or the New World Order, as GHW 'Poppy' Bush called it.
