Problem #1 with that scenario, is I manage fairly Sr. Network Engineering groups. Should I lose my Job in the Greater Kansas City area, there is probably a grand total of a dozen companies who would be interested in hiring someone who deploys Cisco 6509s by the truckload. And, other than Sprint and the Military, I suspect there is nobody out there particularly interested in the deployment of IPv6.

Meanwhile, in Redwood City alone, within walking distance from my house, I can count about 20 companies who might reasonably employ me.

I'll agree there isn't as much competition, but, the high end positions are _very_ few and far between.

Actually there isn't as much competition as you think. There are more employers here in the Bay Area than there are available employees to hire. The only way to get employees for a new company here is to snipe employees from another company. The last time I attended a job fair here (approximately 2 months ago), I had no less than 15 job interviews thrown at me.

Also, it's great to have many "competitor" companies working within a few miles of each other. If you decided to leave a company like Playfish, all the competitor companies like Zynga, Rock You, and Playdom will want to snatch you up in a hurry.
