If psychology has real facts in this area it's not what you post but instead this:  The principle of least interest.

The person with least interest in a relationship controls it.

In the tech boom of the 90s, tech workers were least interested...they could get another job in an hour.  And up went their pay.

We need to distinguish between workers with attractive things to offer, and workers with unattractive capabilities to offer (social justice degrees, women's studies degrees, diversity studies degrees, sociology, etc.).
