I definitely agree that we should assume that they pay each other.  Of  
course, there is also the cooking, childcare, chauffeuring, nannying,  
teaching the kids (if any), amusing each other and so on.  If we stretch our  
imaginations enough, we can make GDP many times higher than it is now for  
every country.  
  
Of course, there is the nagging little question of "after we calculate it,  
what is GDP good for anyway?"
