Taxes have always been high in California, didn't they? It's not like it changed dramatically in the last 5 months compared to the last 5 decades, compared to the rest of the nation. And still, California kept growing.
What changed is the last 5 months is that people have an option not to pay them (by moving and working remote).
I expect California to try some sort of remote worker tax soon to try and stop the bleeding. Best of luck to everyone out in search of greener pastures. Remember not to enact the same city policies that turned California into what it is today.
