I think the issue will be a combination of retaining & attracting qualified workers. I'm in HR and we are already seeing this in many areas. When Economic Developers in our company look at site selection critera, workforce availablity is now at or near the very top of the list. That wasn't the case just 10 years ago. It used to be factors like land availability/cost, tax rates/breaks, utilities, transportation, etc. Now it's a question of do you have - and can you keep - the knowledge workers we need to run our company.
