Several people have said that bad things just don't happen in the Wodehouse universe, but I'm not quite sure it's all of the Wodehouse universe. Psmith encounters tenement buildings, and is appalled by them and sets out to improve the street he saw. (Specifically only the street he saw - that's biting off a big bite, but Psmith never bites off more than he can chew.) "Psmith, Journalist" was written, I believe, before - perhaps well before - the Jeeves and Wooster stories. My guess is that Wodehouse hated suffering far too much to be able to deal with it in his fictional worlds, and perfected the Wooster universe as an escapist place.
