I'm a little shocked at the proposition.

The notion that 'you could feasibly make more money elsewhere, and therefore should leave' is not obvious to me, or I think to most people.

Chicago may have more opportunity than Michigan overall, but that doesn't mean there are not great opportunities in Michigan. But that's within the context of your imperative.

The real answer is that for most people, their job is not the defining artifact of their life, it's a means to support their families, and maybe give them an opportunity to engage with their communities, have hobbies, friends.

I think for young people, in their 20's the notion is a little big different, because moving is exploring and liberating in some ways, but that's only one phase of life.
