I'm not arguing that your real-life experiences aren't real, just that they may not be representative.
My lived experience is somewhere in the middle: I've seen some high earners leave, but more high earners stay. Based on this study, it seems my experience might be more representative of the whole.
Also not sure why you're taking this combative, condescending tone. Seems like you have an axe to grind and are emotionally attached to your position for some reason. But it does seem like you weren't happy in CA, so I'm glad you've found a place to live where you're happier.
