  In 1979 Fradkin and Shenker observed \cite{Frad} that if one considers a
Yang-Mills theory fully Higgsed by virtue of scalar fields in the fundamental
representation of the ${\rm SU}(N)$ gauge group there is no phase transition in
passing from the Higgs regime (weak coupling) to the "QCD confinement" regime
at strong coupling. The above two regimes are continuously connected. We
combine this observations with lessons from supersymmetric gauge theories which
show that the Higgs phase is continuously connected to what is called
"instead-of-confinement" phase rather than the phase with quark confinement. In
the "instead-of-confinement" phase monopoles are confined and play a role of
"constituent" quarks inside hadrons. In contrast, the Seiberg-Witten phase of
quark confinement is not analytically connected to the Higgs phase.
  We propose dedicated lattice studies of Yang-Mills theories with scalar
quarks.
