Things change. Get over it.
Tell NYC that.
I'm all for living where you can afford.
But not everybody on Google is a high payed SW engineer. And there's not only top engineers/managers/designers living in a city.
And for $4300 I can live in a very nice place even in other high valued cities.
If you have owned your home for awhile, your property taxes are not changing that much. Your assessed value starts with the purchase price and increases, at most, 2% each year. This house[2] listed on Zillow is a great example. It sold in 1973 for $32K. For the passed 40 years they've been paying property taxes based on the $32K plus ~2% increase each year (I'm not sure how far back that 2% max increase goes). In 2013, the assessed value was still down at $72K... meaning $997 in property taxes. That same year the house was sold for $875K. Now the assessed value resets to market value and the new property taxes will be like $11k rather than the previous year's $1K. So even though the housing prices skyrocketed around them, the previous owner of the house wasn't really effected by that increase.

I suppose you believe that NYC and SF have rent control because housing is so expensive there.
Have you considered the possibility that you have it backwards?
But I certainly don't think that rent-control is the primary driver of high housing costs in SF/NY.
If landlords didn't want gouge by asking for fair market value for their properties, all of the old guard would still be living in SF.
