“half the world doesn’t know how the other three quarters live.” — P. G. Wodehouse.
It’s more than a joke. It’s a much smarter line than the more familiar “...other half lives” (which is from an 189- photo essay by Jacob Riis about slums of New York)

We always imagine our reference social class to be bigger than it is. The Wodehouse version suggests we always think of ourselves as part of a 50% class if we can, by some dimension. But that choice is likely more like 1/3.
