We address the question of the relation between supersymmetry breaking and
the origin of flavor in the context of CP violating phenomena. We prove that,
in the absence of the Cabibbo-Kobayashi-Maskawa phase, a general Minimal
Supersymmetric Standard Model with all possible phases in the soft-breaking
terms, but no new flavor structure beyond the usual Yukawa matrices, can never
give a sizeable contribution to ϵK​, ϵ′/ϵ or
hadronic B0 CP asymmetries. Observation of supersymmetric contributions to
CP asymmetries in B decays would hint at a non-flavor blind mechanism of
supersymmetry breaking.Comment: Reference added. 7 pages, no figure
