People that got wealth in from selling a business soon realize that the power thier millions or billions brings them is nothing compared to the power wielded by politicians proximal the money printer or the power of the inflexibility of government policy whether by incompetence or design.

A national example of this could be Vivek Ramaswamy, but where I really see this is at the state or local level where a wealthy guy that is used to being able to pay people to do just about anything runs headlong into a deadlock of local government bureaucracy that prevents him from getting something he wants and it makes him so mad he decides to run for office. Usually these guys spend a ton of money and rarely are elected.
