EconProf, you keep harping on the long term fundamentals in which AZ is better off than CA. I’ve never heard anyone say a large retiree base (which you specifically mention) as a long term fundamental, or a positive.
Each place has things that attract and things that detract. AZ and NV are no different. However I’d be very careful of trumpeting the positives of places who’s basic existence is premised on people being ejected from California (whether by choice or economics).
You can fix tax policy. You can’t fix no water or insufferable heat. California has problems and they are massive. They are however FIXABLE.
