It is something to think about. Service jobs were appealing because they seemed impossible/impractical to outsource, but its not necessarily the case with many anymore. Doctors/lawyers/realtors and the like will always be protected by their professional associations creating a barrier to entry through licensing and legislation. Maybe we'll see a rise in these sorts of regulatory boards for other professions.

Maybe we'll see a rise in business creation when people can't get a job working for someone else. It happens during every recession. I wonder what the impact would be of corporate jobs becoming increasingly rare.
