Good CEOs are good communicators. Most CEOs, like literally any other profession, are not. People like Jobs are exceptions, and for every one of them there are a hundred shitty CEOs who are neither talented nor intelligent, even among the companies that are still alive, but they don’t get discussed here because this is a site about making money first, and tech second, and the crowd here doesn’t like hearing it’s all bullshit. For every Apple there are a hundred Shitty Integrated, Inc. companies that no one talks about, and every one has a CEO.
There are no qualifications to be a CEO, ultimately, except the board happens to want you as CEO.
The point is that FU money is the point at which you have enough that you can walk away from situations that you don't agree with without that impacting the rest of your financial life in any manner.
In other words, it's retirement but at a younger age.
It's not to say you don't walk away from situations you don't agree with before you have FU money. It's just that you're at a point where it won't impact the rest of your financial life.
I don't really see why it has such a negative connotation.
/edit I should add this term is usually used in terms of someone who has spent 20+ years in a career (and typically the same company) and is at loggerheads with upper management in an unresolvable situation and is about to get forced out over the situation. i.e., upper mgmt is doing something that person believe is wrong, unethical, etc.
