Maybe I'm am outlier, but I doubt it; I think most people understand that the billionaire thing is a pipe-dream, and they work every day to pay their bills and if you're lucky to also work on stuff you're interested in. How exactly would that be affected by lowering the wealth-hoarding you're allowed to do?
I think that the side effects of a wealth tax might just end VC investing in high valuation companies altogether. I don't know if many people on HN see that as a positive.
I think most people would still be willing to keep working on stuff, and I don't see why VCs would stop investing in high-value companies altogether.
[0] Anecdotal, but that was the way to get an apartment for my parents' generation back in Soviet Union and I really don't want to see it here again.
