Do you realise what "147 corporations" even means? In terms of scale?
Here's some perspective on 147 corporations
- there are hundreds of thousands of related companies, subsidiaries, and various legal entities
- they would employ millions of people
- these millions of people make trillions of tiny decisions on their own every day, which combine to affect and influence the operation of these corporations on a level that would be impossible to quantify
- this theory also basically discounts the effects of external influences - that is every other corporation, government, etc., and not to mention micro and macro economic influences
- plus a bunch of other things
Whilst no doubt these corporation exert a lot of influence on the world, it is irrational to think they somehow form an entity that conspires to and actually does control the world.
