The parents of these guys are bums or unlucky and their kids are "white trash."
In the stage play, this is alluded to in dialogue too, but differently, with Shrank insulting the parents right to the Jets' faces. It's not spelled out the same way as in the new film, but I think it's implied that these aren't happy families in general at all. And of course in "Krupke" there are similar allusions. |
