That's a very narrow view...

The people in charge of companies usually have large amounts of stock in their companies... And often bonuses tied to metrics that often includes stock. If their share price drops 50%, that's a personal "net worth" and/or "salary" loss which, unlike most people, they have bounce-back control.

"We need to trim the workforce", "improve margins", "show we are still a solid company"

The above doesn't just happen in AI/Tech stocks, it happens EVERYWHERE... Small business owners see their retirement portfolio hurt, they can't fix those companies, but they might reevaluate what they do in the next 2-3 years so they can get their retirement back on track... How do they increase profits while lowing costs? Try to cut staff/hours, find (perhaps foreign?) cheaper suppliers.

I think AI stock bubble bursting won't result in large scale layoffs, I think it will result in large-scale _trimming_ across the economy, which is almost worse. AI will be expected to fill in the gaps to increase productivity for less than the cost of an employee, which means slower rehiring .. AI will rebound at a "more correct" evaluation. And hiring will slowly pick up as companies see they still need people to produce.

Viewing the stock market as purely a casino -- the executives are the house at various casinos... and the house likes to win at the expense of the players (anyone not a casino)
