Obviously if inequality gets to a certain point, where you don't have a solid middle class anymore - that's problematic. I'm just curious about your stance because I too feel like Jeff being rich doesn't really make my life any worse.
How does Bezos harm you? I don't want to put the blame squarely on his shoulders but I would like to point out an apparent dynamic.

There is definitely a narrative that can explain why Bezos fortune is rightfully his down to the last cent and why he is a net positive in this world. And it wouldn't necessarily be incorrect. However you can't avoid the fact that his wealth is manifasted as unaccountable power. A society plagued by unaccountable power, which is what I believe that inequality ultimately is, is not healthy.
