Amazon aggressively reinvests its extremely large and stable earnings into the business which Bezos owns a large part of and controls actively. Both he and his ex-wife have realized extremely important liquid wealth by selling a significant part of their stakes. How would you measure his wealth?
The UK has a similar share (actually slightly smaller) with over 10 times the population.
The GDP difference between the US and Europe is fifty times larger than one rich person's own income? This isn't actually a great argument dismissing the suggestion that US wealth is extremely concentrated.
His income last year was around $60 billion, or $200 per person (of any age) in the United States. While last year was exceptional, all of his wealth ($600 per capita) was income in the last 20 or so years, most of it in the last 10. And his ex-wife Mackenzie Scott kept 25% of their combined wealth when they separated.
So it's simply not true that his contribution to GDP looks completely trivial even when compared to total US GDP.
They will spread these habits to their students and colleagues and as they move between institutions. UC is huge across all the constituent colleges and many parts of it are extremely prestigious, so UC grad students are the sort of people who will often end up as professors in other institutions.
Abstinence as a strategy is not in and of itself flawed. The way lots of people cope with the dangers of heroin is simply by never trying it their whole life. Lots of addicts adopt a strategy of permanent abstinence, forever.
Some things are very harmful. I don't think we all need to try all to them, just to make sure.
