I would add one more: me too-ism from CEOs following Musk after the twitter reductions. I think many tech CEOs (e.g., Zuck) hate their workforce with a passion and used the layoff culture to unwind things and bring their workforce to heel (you might be less vocal in this sort of environment... think of the activists that used to work at Google).

Now that someone's said to Trump's face that Wall Street thinks he always chickens out, he may or may not stop doing it.
