That’s…capitalism. In a profit-seeking society, there’s no greater profit than taking control of the society’s government. There’s no such thing as “crony capitalism” if that is what you are referring to. It’s all a part of the game. Any sufficiently powerful company will eventually attempt to manipulate the law and regulations for their own gain.

The Soviet Union is basically what it would look like if a single corporation managed to completely take over society and push out all competition. That’s why some people argue that it was a type of society known as “state capitalist”, instead of communist, since they never actually did away with money, class, or hierarchy.

Another good example would be “Buy-N-Large” from the movie “Wall-E”, although from reading the backstory on them, it seems like a more benevolent entity than we would expect from such a monopoly. Faced with declining profits from a failing economy and environment due to their grip on it, they implemented a system of universal income so that they could continue to have customers. They slowly became the world government and effectively operated as one.
