  Some implications of flavour unification in supersymmetric Grand Unified
Theories are briefly reviewed. We argue that the gauge hierarchy phenomenon
properly interpreted in terms of the natural missing VEV solution for the
adjoint scalar in general SU(N) SUSY GUT could give insight into both of the
basic features of low-energy physics accommodated in MSSM just as some strict
colour-flavour (or colour-family) interrelation, so the SU(2) symmetry
structure of weak interactions. There, apart from the ordinary triple matter of
MSSM, just three families of the pseudo-Goldstone states appear in the minimal
SU(8) theory to be of necessity detected at a TeV scale.
