Yes, we have lost a net of 3.4 Million CA residents (using Lippy's #'s) over 20 years to various other states like TX, AZ, OR, NV, etc. due to the CA economy, regulations, high taxes, etc. The migration rate has slowed too. But, we've also had three major recessions in those 20 years, including the biggee in 2008-2009, which greatly affected CA and we're also attempting to protect our environment and clean our air.
CA is the most populus state at roughly 38 Million residents, so less than 10% have left since 1990. Not great, but it doesn't seem like a BFD to me. Our state continues to grow with foreign migration,
just like ALL our families came from somewhere else, our air is cleaning up, the enviroment is getting protected and they're predicting a big budget surplus for this fiscal year. The future looks bright to me.
In the last election (2013), the City of Sonoma (wine country) did
not pass a hotel limitation measure, so Californians are not all about anti-growth.
CA can't grow forever and CA is far from perfect. We will run out of space. Other states have lots of space. So, you can see the glass as half-empty or half-full. I choose to see it as half-full.
