I agree with you entirely, but what I'd say is that often policy can get in the way and pose obstacles and not give people the ability to move from one place to another if they so choose. There are numerous reasons why that could happen. There could be incentives to stay back home, such as the way the employment insurance program is structured. It's structured so that people would have a better system of return if they were to file their claims in their home province. There are other things as well, such as people who under 35 years and are repeat users of the employment insurance program falling under the same requirements as anyone else. There are numerous ways in which policy can get in the way of labour mobility, and I'd like to draw that to your attention.
I agree with you that it's not necessarily our say whether they should or shouldn't, but there are also ways of allowing them to make that choice themselves.
