  A careful renormalization group analysis of the electroweak Standard Model,
considered as a low energy effective theory, reveals that there is no hierarchy
problem in the broken phase of the SM. In the broken phase a light Higgs turns
out to be natural as it appears self-protected and self-tuned by the
spontaneous symmetry breaking. It means that the scalar Higgs needs not be
protected by any extra symmetry, specifically super symmetry, in order not to
be much heavier than the other SM particles, which are protected by gauge- or
chiral-symmetry. Thus the existence of quadratic cutoff effects in the SM
cannot motivate the need for a super symmetric extensions of the SM, but in
contrast plays an important role in triggering the electroweak phase transition
at a scale about 10^{17} GeV and in shaping the Higgs potential in the early
universe to drive inflation as supported by observation. The impact on the
inflation profile of the quadratically enhanced bare Higgs mass term in the
unbroken phase is discussed in some detail. My analysis suggests that inflation
in the early universe is a direct consequence of the SM Higgs sector with its
quadratic enhancement of the bare Higgs mass term
