The way companies and ownership work that's actually quite possible and reasonable.

The count of shares you have represent how much control you have over a company.

If you own a company private or public that does well and you want to retain control of it, you need to own at least over 50% of the voting rights.

Wanting to control your company isn't that outlandish a desire. There have been plenty of stories of people getting ousted over the years.

Simply owning a company that does well could result in you becoming a billionaire.

And I'm not arguing against what the other poster said, to get to that point there's gotta be some level of ruthlessness, disregard for others etc.

Just that there is actually a reason to desire more even if you have all your needs met. Being rich shouldn't mean you have to give up control, and its really hard to change corporate structure once public.

Facebook for example is set up where Zuckerberg has >50% voting rights. Is that bad? Probably. But it's his company, and I don't fault him for wanting to keep it that way.

Edit: and yes I'm aware of Zucks fuckery to get / maintain that share and his co-founders
