In a way I commend the likes of Musk for galvanizing people against billionaires and advancing social movements. He's so dislikable that it's productive.
People don't always grasp the amount of money a billionaire has. Let's put it in perspective:
A billionaire looks at $200,000 the same way a person with a $100,000 salary looks at $20 (for reference, a 1-millionaire looks at $200 the same).
It's also worth noting the power billionaires have relative to their country's size. Looking at Number of billionaires per million people. You could probably take this and weigh it further against the median per-capita GDP to see how much clout one billionaire has versus the population. For example, while India has a low # of billionaires / million people, the power the ~169 billionaires there have an overwhelming share of the total wealth of that nation.
