I would be willing to bet (well a little anyway)
that the population of even L.A. has increased over the last 5 years (traffic is still just as bad anyway), and they are the worst for Tax-with-no-good-service-in-return.
If and when the home building starts to get going in earnest in SoCal I think you will see the net inflow go up quite dramatically.,
Also some of the states that were so glad to grow are starting to see real issues too, so I think they will be in the same boat as far as taxes fairly quickly.
Property Taxes in TX can be very high and Texas cities are becoming just as traffic logged and Smog is becoming a real problem now in most TX cities.
