It is shown that in supersymmetric SU(N) models with N>5 the so-called 'doubly lopsided' mass matrix structure can emerge in a natural way. The nontrivial flavor structure is entirely accounted for by the SU(N) gauge symmetry and supersymmetry, without any 'flavor symmetry'. The hierarchy among the families results directly from a hierarchy of scales in the chain of breaking from SU(N) to the standard model group. A simple SU(7) example is presented.
