We examine an effective field theory inspired by Little Flavor that demonstrates a new paradigm for generating quark and lepton masses in which the scale of new flavor physics can be at the few TeV level, and new Z' and W' bosons are predicted. The model possesses an approximate U(2)2 vector symmetry, not the full approximate U(2)5 chiral symmetry of the Standard Model or Minimal Flavor Violation models, yet flavor changing neutral currents are sufficiently suppressed. Additionally, lepton flavor violating processes, such as μ→ 3e, lie naturally just below experimental bounds and the down quark mass can be radiatively generated.
