Not that these things don't happen regardless but artificially inflated capital (AKA debt) perpetuates the issue.
Maybe we should realize that increasing debt via banks and financial products is not good in of itself. Especially when we contrast it with investing in technology and workers.

If you had just read the article or looked at the report, you'd see that the time frame involved includes the March 2020 crash, which in fact did not cause a massive cut for billionaires, who maintained 2.0% of the worlds wealth throughout.
It’s all a function of two things: 1. what percentage of your wealth is where, (ie home, stock market, checking account) and 2. Even if you and a rich man are both 80% in the stock market, he’ll come out in absolute terms having made more money.
Is that fair? I think so. Both made the same percentage. And if it drops, he’ll lose more absolute money, too.
The words "all" and "doubled" are an exaggeration, though.
Who and how?
