They didn't become wealthy by accident. They worked hard to make their money.So just because two absurdly wealthy entities prop-up each other makes everything OK... fffs xD
The fact that someone becomes wealthy doesn't make him/her a bad person.
It's business. In politics it's the same thing. Countries make alliances to help each other and combine their power for dominance.
This later generation is all about crying and complaining about everything: "Oooh, too poor! Oooh, too wealthy! Oooh, too expensive! Oooh, too cheap! Oooh, I want more choices! Oooh, too many choices! Oooh, why is this one the first choice!". A never-ending whinning loop.
