“When the tide goes out we will find out who has no shorts on.”
As an example here, in the 2022 (relatively mild) stock market downturn, when the S&P 500 gave back about 20%, TSLA dropped from a peak in the low 400s, to a low of 122... roughly a 70% drop peak to peak. It's back to ~400 now, and it could go higher again. But, in the next downturn, it could go a lot lower.
The rest of the world wants dollars, and as long as they do, the US benefits massively from that demand, and it would be foolish not to satisfy that demand, as it's pure benefit to the US.
It seems that many are devoted to ending the status of the dollar as the reserve currency of the world, but it's a strange and subversive thing for any US resident to want or desire.
