This… is how it has been for over a century, at this point - with reference to American billionaires specifically. Much of the shape of the modern world is the outcome of political influence by American financial giants, from pre-war industrial staging to post-war outright restructuring of global financial systems to ensure capital flows were favourable to the U.S. - I mean, for God’s sake, Bretton Woods, lend lease, the U.K. aerospace and nuclear programmes.
Strip it back to just billionaires, or their equivalent over time, and thus it always was.
People talk about the “new world order” as though this is some novel concept - but you can saunter back in time past the east India company, the bourbons, the holy Roman emperors, Rome, Greece, Sumeria, and see the same pattern played out throughout history. True power sits with wealth - an impoverished ruler relies on others for his means, and has no power of his own.
The wealthy, those with power, have always decided for the rest, have always had outsized influence, as long as there have been societies with the concept of “mine” and “yours”.
