  We show that one can describe the quark and lepton masses with a single
anomaly-free U(1) flavor symmetry provided a single order one parameter is
enhanced by roughly 4-5. The flavor symmetry can be seen to arise from inside
the $E_6$ symmetry group in such a way that it commutes with the SU(5) grand
unified gauge group. The scenario does not distinguish between the left-handed
lepton doublets and hence is a model of neutrino anarchy. It can therefore
account for the large mixing observed in atmospheric neutrino experiments and
predicts that the solar neutrino oscillation data is consistent with the large
mixing angle solution of matter-enhanced oscillations.
