.......If you offshore the manufacturing jobs, you are left with...services? Banking? Last time I was in the UK, about 5 years ago, I couldn't get over how many people were driving around, all the time! Where were the going, what were they doing, and didn't they have any work to do? I still don't have the answer to that one.
Would you like me to go through your list?
Nurses, doctors, dentists - people do like their healthcare. Surprisingly to some, I would give them a tick, too. It's a yes!
Charity workers, teachers, university lecturers. Ahh, now we are getting into trouble...some yes, but some (most?) an emphatic no.
Scientists, engineers, researchers - yes, but quite a few of these have been offshored to China and the Orient. Isn't that the point?
Vets, farmers....farmers grow food, and without food people die, so we can tick that one as useful.
Government statistics:
