Cash or Credit...Gotta Get It!

So I was speaking with a male friend at work. He is engaged to this young lady (very, very sweet btw), but he isn't really in love with her...When a few of us started to ask why he was still with her, the first thing he said was "she has good credit". Is that something akin to great personality, treats me well, good head on her shoulders?? Is this a result of the recession?! What did I miss?!!
