I gave you the dependency per capita, it means very little if there are rich people here, there are rich people everywhere.
Frankly, I am fine with the rich paying more, but in time of disaster to withhold help while giving help for swing states 6 months after a much smaller disaster happened - yup, I am not fine with that one bit and nor should you.
Oregon is #27 in resident dependency on federal aid, California is #44 - so your argument is not reasonable - are you upset that Oregon gets help in other ways than California? The point here is how much help is received - and the fact is that California residents get very little compared to the rest of the country while paying the most in federal taxes - so withholding aid during a disaster is deplorable.
I also am not a big fan of telling people where to live - they should make their own decisions - but if they contribute to a shared pot - they should not be singled out in trying time. For the record, I already made my residency decision when I moved from Portland to California - and it was certainly not a financial cost of living decision - because as expensive as Portland is, California is more expensive, unfortunately.
