Obviously, there could be informational barriers. People may not know about opportunities. It's costly to move, and there is a lot of risk. There may be scope for government programs to support that type of thing. It could be expensive.
My view is that I'm a little bit of a laissez-faire economist on a lot of these issues. I do support our social safety net. I think we do want, as the other speakers have said, to help people up when they're down. However, whenever we do a program to try to help people move or change or retrain, I think we should be doing a pretty rigorous cost-benefit analysis.
