Billionaires wield untold power and influence over the economy and government and are unelected and effectively mini-dictators. They are incredibly powerful because of their wealth and have effectively no checks and balances. And because of all this, they often come with or develop egomaniacal and sociopathic tendencies that further remove them from the reality of common people.
That’s why its significant. Don’t act as if billionaires are just “one of us” when it comes to influence.
I would consider billionaires some of the biggest threats to democracy and national security.
