Disagree. Willingness to move where you receive the best job offers is one of the key factors to strong career progress and earning potential.

Unless you happen to both be in the same line of work and have that line of work be centralised in one city so hard that your best offers are pretty much always going to be there anyway, you can only maximise one of your careers. The other person is turning down offers they otherwise could have taken, moving to locations they otherwise would not have, at times when they otherwise would not have. It's a huge sacrifice even if both people are full time employed and no kids are in the picture.

Deciding to try to spend the rest of your life living with another person is the opportunity cost. Marriage and alimony are the tools that try to balance that out and make it fairer.
