CMV: Fame, money, and power negatively impacts a person's personality.

I believe that fame, money, and power have effects on people which make them full of themselves, often more worried about what others actually think of them (despite various publicity stunts), and generally less likeable as individuals.  

And I don't think you need to be a pop star, a billionaire, or the President for the negative factors to start having a negative impact on people.  I think even more modest amounts of fame, money, and power often goes to people's heads and makes them less pleasant overall.  

At the same time, and contributing to the problem, is the culture of celebrity worship and cronyism which serves to keep people propped up even after fame, money, and power have had major impacts on a person's personality and worldview.  Additionally, it's hard to get around the cult of personality surrounding these people because of both the public's appreciation for past successes and because famous, wealthy, and powerful people often tend to appeal the lowest common denominator or the lowest common denominator of a particular subgroup.  So, for example, a rock star might be more inclined to make more formulaic and bland music to maintain their success --- thereby still getting appreciation for their earlier work but also earning new fans who like them because they are now much more generally palatable.  Similarly, a politician might tend to move away from their original values as they attain more power so that they continue achieving power --- even as their moral and political compass has changed their goals.  But the public still backs them because they once presented good ideas and now they are presenting their bland new ideas in slick packaging for the voting public to consume.  And in terms of wealth... I think people tend to increasingly become more materialistic even as they put on displays of using their wealth in positive ways.  

Now I'm not saying their aren't the occassional exceptions to the rule, but generally speaking, and overwhelmingly, I believe that me, money, and power negatively impacts a person's personality.  So you can provide anecdotal evidence of this person still seeming to be the same old guy who never forgot where he came from or whatever, but even then I'd say that's either rare or that the person has actually changed for the worse in ways that aren't readily acknowledged.  

Generally speaking, but overwhelmingly, in most cases, I believe this to be true.

There seems to be a massive potential for confirmation bias in this view. Namely, the people who have fame, money and/or power and are negatively impacted are far more likely to be noticed.

A celebrity who has fame and deals with it but keeps their private life to themselves and doesn't go out of their way to flaunt fame is naturally going to be on your radar less than someone constantly doing things that draw attention.

A rich person who doesn't flaunt their wealth; who drives a normal car, owns a normal house, etc, would likely never even be known as rich to anyone who didn't ask. Lots of rich people are also extremely philanthropic. Hell, time and money can even make people seem better than they were. Bill Gates was not seen positively (As a person) when Microsoft was growing. Nowadays? He is hugely popular because of his charity.

A person who gains power and uses it to make positive change in line with their role is going to be pretty unremarkable from the outside. A corrupt politician will have scandal after scandal. A beneficial bill might get a couple of days of coverage, on average. A major scandal can develop over weeks or months.
