Is anyone else getting bored with this kind of “analysis”? Yes—people in the 99.9th percentile are significantly more than people in the 99th percentile. “Never mind the 0.01 percent. Let’s talk about the 0.0001%!” would be even more crazy, considering the exponential distribution of wealth.
People who write don't earn a great deal of money. Nor (typically) do they have the potential to do so. Other professions can at least dream that they will hit it big or earn a good steady income if that is not the case. People at the bottom can't even dream but 'they know their place'. News articles with head lines like that draw readers sure but I think it's more than that ('people who write...'). This is human nature. Very generally the middle class that are employed and not taking on credit card debt and spending over their means (which they do) don't care that there are super wealthy people.
What is to stop people in some dirt poor foreign country from talking about how it's not fair that people in the US, even our poorest, very likely have it better than they do? (Well nobody other than the writers in our country will say anything and quite frankly nobody in our country would care enough to give them anything that we have so it doesn't matter). When was the last time you heard of a tax specifically to help people in dirt poor countries? (Not talking about aid but actual 'we will take your income', well never).
You know what has changed more than anything? What we know about what others are earning and what they have that is what material goods.
As many older HN readers will probably agree when I was growing up their were the Rockefellers, Howard Hughes and maybe a few other people. There were movie stars and the Beverly Hillbillies. You didn't really care that they were wealthy it was just the way it was. There was no revolt of the masses. Sure there are more people will money today but what there is grossly more of is attention and that it's in everyone's face (and of course the people who write and broadcast about it).
