Productive wealth is a good thing. It's what made our current society possible. Unproductive wealth is the real devil, the hoarding of inelastic goods like land, gold, and oil. I strongly prefer a society which permits the existence of Jeff Bezos over one which does not. Of course, more strongly than that, I prefer a society which taxes inelastic goods and negative externalities and returns that wealth to the public…
What do you mean by "hoarding"? I don't think any living person owns enough land, gold or oil to represent even tiny percentage of the overall market. The whole Russia, for comparison, owns 12% of oil market. So if you personally owned all the oil in Russia (by any measure an achievement far beyond the wildest dreams even of the richest Russian oligarchs, who still have to share among many others) you'd still be just one of the players. So I don't think those mystical "hoarders" really are as scary as you seem to think they are.
