All your points are correct from my standpoint.
After spending 7 years in sunny and colourful Berkeley, CA, I have decided to leave the states for good. Now after 7 years, I am more than glad for what I did - my kid is getting quality education and is able to play with other kids outdoors without fear of being kindapped for internal organs or shot as a bystander in random gang shooting.
Tap water quality is fine, but I still don't have courage to drink it - I must say I didn't drink California tap water either.
And as an software developer, I am able to complete jobs all over the world - online - sitting in my comfy chair.
