Wow, that&#x27;s seriously jaded stuff... Selecting mates based on lowering the cost of eventual divorce!<p>I&#x27;d bet it has more to do with maintaining current (or expected) lifestyle. If you&#x27;re used to a top-5% income, with the lifestyle that income enables, marrying &quot;down&quot; has a real impact. The effect would be even more noticeable in an expensive metropolitan area like NorCal, NYC, etc.
