Worrying numbers

At times I wonder if our brains are ill adapted to dealing with crowds of more than 100 people. Here I am well past 30,000 faces, all individual and still no idea how to handle them. The marketing perspective would be to sort out a dozen masterpieces and burn the rest for a grand rise in value.
Perhaps that's what celebrities are for: We can't even think of millions of people who are each different and valuable by themselves. So we single out a few dozen stars and only worry about their lives. That way, we have reduced a whole society to an extended family sized unit in our minds. There's your immediate family and friends and then a handful of celebrities to stand for everyone else.
