I’d be pissed if I was one of these companies that supposedly already started building factories in the USA

The traditional “leverage” is just the standard CEO - stockholder relationship. The CEO manages the company well and the stockholders reward the CEO with payment and/or by making the stock price go up by buying more and/or not selling. IMO that basic relationship broke down a while ago, but the stock market has been unhinged for so long that it seemed to not matter.

One of those is actually two possible outcomes. There’s TSLA Tanks (the stock) and TSLA Tanks (TSLA becomes an arms dealer), and they aren’t mutually exclusive.
