At least as long as this bit of research pans out.
Of course, I'm inclined to think that the whole "bad parent" thing crosses the lines of ugly/beautiful. I work in a Barnes & Noble in one of the richest areas in Southern California. Based solely on my informal observations over the last 18 months I can say the following:
 Money and physical beauty seem to go hand in hand,
 Good-looking, rich parents are, at least in terms of parenting, completely, utterly retarded, capable only of raising loud, loping hordes of evil, illiterate monster-children who enjoy smearing poo on bathroom walls, reading the "Sex Position Of The Day" books like they were SAT study guides, and using $80 books as coasters in the cafe.
Bring on the ugly, I say. At least we less-than-beautiful people still understand the concept of public shame.
Well, except for Rosie O'Donnell, that is.
