alt Hacker News> People should not be allowed to accumulate capital beyond $X, yes.
The term "capital" is an abstraction that's not helpful here. The big "wealth" numbers are all about equity ownership in highly valued companies. Bezos owns 9% of Amazon stock. That's why he's "rich." What should happen to that stock? What happens to his voting control over Amazon?
The problem is people that rich don't own anything. It's all shell corporations and LLCs and money borrowed against those shares (so no need to pay any taxes). But they clearly have access to yacht money. We're not going to write an airtight law in the comments section. We can just ignore paper wealth and ownership stakes for the purposes of wealth redistribution.
The question boils down to a feeling that when the revolution comes, that no one person needs more than, say, $100 million for themselves, or not. Trying to distract the conversation into defining "for themselves" will only prolong your time before the firing squad, comrad.
