"the problem with wealth inequality is wealth inequality"
Just one nit - the problem with wealth inequality is that it perpetuates wealth inequality (and Piketty has detailed evidence for that).
We have had a lot of back and forth in multiple threads for this post. It is helping me clarify my thoughts, which for now can be summarized as:
1. Today, rich people have much better life than poor people.
2. Rich have higher chance of being rich tomorrow than poor folks. So that means they and their heirs have a higher chance of having a better life perpetually than ordinary folks and their heirs.
3. I don't begrudge better lifestyle for those who earned it (Gates, Zuck, Buffet...), but I do think its grossly unfair to enjoy better lifestyle just because you were born to rich parents (Walton heirs, Koch heirs, Paris Hilton...).
4. If you think capitalism has improved things so much that differences in wealth hardly matter (or such will be the case in future), kindly provide me evidence. I don't see it anywhere in my observations - eg. first class vs economy class experience in air travel, public schools vs private schools in the USA, job prospects for ivy league vs third tier univs, or even longevity[1] - rich people's life is better in almost all aspects (some of those aspects might frivolous but some are very meaningful).
