It's impossible to answer in a vacuum. We live where we live because we're 10 minutes from my wife's two sisters, my wife's parents, and 3 cousins our kids love to play with. Generally, I think the only way we're moving is if they move first. Because my wife's whole family is here. And she spends multiple days per week with them. As do our kids. The idea that she should be supportive of me tearing her away from this…
The idea that a well compensated, educated adult can't survive without an extensive support structure for a few years is questionable. Hell, I haven't had a support system at all - my family was actively abusive and antagonsitic to me, and yet I was able to successfully build a career, family, and so on. It's just as likely codependancy as it would be support.
Financially, sure. In terms of mental health and feelings of isolation (especially for the wife, who won't have a high-flying career to distract her/build new contacts in), it's absolutely a problem.
