  We follow the example of Cabibbo by revising the Standard Model (SM) to
present a universal mass structure for fermions. A universal Higgs coupling for
each species of fundamental fermions moves the SM towards a Theory of Matter,
albeit without correctly describing the observed mass spectrum. It exposes a
need for a complete Theory of Matter to include components from physics beyond
the Standard Model (BSM). Describing the effect of these components
phenomenologically provides a means to infer the nature of some of the BSM
physics required. Our results also provide constraints on some BSM matrix
elements. Here we apply this concept to quarks; the application to leptons will
appear in a separate paper. An immediate benefit for theory is the reduction of
the largest fine structure constant for the Higgs coupling to fermions by an
order of magnitude, which improves the perturbative appearance of the weak
interactions. The small mixing of the third generation of each fermion in the
fermion families to the others is attributed to the small BSM perturbations
that produce the small mass ratio of the lighter generations to the most
massive one.
