Means, language competence, and and time. I wouldn’t want to live abroad during child-tearing years (assuming a hypothetical significant other isn’t herself foreign). But before (early-mid twenties) or after (fifties?) would be fine, assuming I had a well-paying job doing what I wanted and serving my ideals.
I actually disagree with you on that. I've definitely thought about temporarily moving for a year or two when my child is in the age 12-16 range or so. I think he (and most others) would love it, and be a better person for it.
