yeah i can see your point but many professions are located within virtual offices which makes relocation a lot easier
or when you see mergers such as fleet and bank of america they shift certain operations certain opening up new opportunities in different venues that are cheaper to operate and cheaper economically for the employees
kind of like a chain reaction but even without these change in venues for these corporations like said people are very mobile
example an investment portfolio manager most of the business takes place behind the scene which opens up a choice of location of where one would like to reside
here is the link for the migration story I spoke previously about, so I guess its an easier decison to relocate than anticipated
