Apple is a beneficiary of the environment in the Bay Area - the fact they are at least aware of the issue should be encouraged.

The Bay Area represents a very culturally and intellectually diverse area that resulted from the seeds planted in the 1950's (and arguably earlier). The real issue is that the rest of the country denied this opportunity for themselves meaning that all of these creative engineers moved to the Bay Area (and Boston and Austin, etc.). Ever hear of Haight-Ashbury, Berkeley, etc.? This would easily self-balance once the rest of the US caught up.
