We discuss two classes of theories that have something to say about fourth generation quark and lepton masses (as well as Higgs). One is based upon universality of low energy parameters as determined by the renormalization group: infra-red fixed points. The other is a toy model of geometric heirarchy which may arise in a novel scheme of dimensional reduction without compactification.
