I think the shamelessness from Paris Hilton of a different kind than the shamelessness of the 2016 candidate. The former is of the "give them something to hate/gawk at/despise" whereas the latter is a byproduct (first), and results in (second), the breakdown of institutions. When our institutions can't be trusted, the advantage that we thought we were supposed to gain from playing by their rules (stability, fairness, equality) don't seem like they outweigh the disadvantages (waiting and thinking, instead of acting immediately). So we turn to greed and tribalism, and we like to see that legitimized by our role models.
