Basically what you see these days is PR teams together with legal teams acting like individual that hired them. There are exceptions, but they are outliers in say Trump style, not these billionaires. Same, heck even more for politics.
It can be easily transferred into personal or professional relationships. For me at least, this analysis works 100% of the time when for example rest of friends or family struggle hard to understand actions of some individuals. Just point them to their previous actions and see the consistency emerging. This is how you can easily work with various people if you are smart but lack social skills, just observe actions and ignore blah.
People simply don't change, they may reflect change in their environment but thats it. Unless we talk about 2 decades+ since last encounter, but even then it may be just more polished PR.
