There's a lot to be said for that, but those companies don't really rule the world anymore. AT&T is gone (or has been downsized to the point where it doesn't matter). IBM has been overtaken by Microsoft, Apple, and Google. Exxon and GM take what they can get from Biden. Chemical companies have been outpaced by pharmaceuticals. Foreign firms do more and more of the world's manufacturing.
Point being a few oligarchs, like Bill Gates are now running the show.
