Query: Mass Hierarchies, Hidden Symmetry and Maximal CP-Violation   In view of the observed strong hierarchy of the quark and lepton masses and
of the flavor mixing angles it is argued that the description of flavor mixing
must take this into account. One particular interesting way to describe the
flavor mixing, which, however, is not the one used today, emerges, which is
particularly suited for models of quark mass matrices based on flavor
symmetries. We conclude that the unitarity triangle important for B physics
should be close to or identical to a rectangular triangle. CP violation is
maximal in this sense.
