Love Thy PlayStation, Love Thy Self
Okay, I get it...I guess....

Thing is, there's other benefits to a wife/husband that don't come from a PlayStation (or another similar item):

• Sex. And no, masturbation doesn't count -- it's not nearly as satisfying, especially when you get the other person to come. You'd be surprised at the ego boost you get from getting the other person to come, especially repeatedly.
  
• Division of Labor. One person takes care of dinner, the other does the yard. One person holds down the fort, the other earns enough to keep it warm dry and shiny. One person rises up the corporate ladder while the other makes sure he looks the part. One person makes music (or art) while the other makes sure the art can be made and sold. Two people can live cheaper than EITHER could alone. You get the point.
• Roots. From personal experience: I tended to go out every night when I was alone. Now, with someone, I go out maybe once a week (sometimes less) and am more satisfied with the nightlife I imbibe.
  
• Balance. Simply put, two people together can balance each other out, holding back each other's excesses and weaknesses. Where one person is blind, the other can see and catch; thereby correcting possibly fatal mistakes. It's no accident that single people die sooner, single men average a decade less life than married men.
  
• Investment Grows with Time. As your SO/spouse grows older, they grow in worth (they know you , you know them, you grow comfortable). Video games tend to grow stale as they grow older; even the long-lasting titles need revivification every so often.
  

I'm sure there's other ways a human beats out a PlayStation. However, when you consider that $100,000/year is more than most people earn even today, it should be obvious that a long-time love gives dividends that outpace whatever benefits a single life may give.
