Exactly this. Finance transparency should be a requirement for public officials. I honestly don’t care if my politician has a NW of 10 million. I do care if that’s tied to industries they are supposed to be regulating. I also care if they started out with nothing and became millionaires after joining politics.
That said, billionaires should be barred from ever interacting with politics. Congratulations, you won capitalism, now leave the rest of us alone.
