*sigh* The core concept of progressivism is what most of us want - policy based on our current best understanding of how the natural and social worlds work. The fact that it's been used to promote questionable policies in the past shows its flexibility: as we learn more, those policies are abandoned. The alternative, blindly holding on to policies that have been proven not to work (supply side economics on the right, Marxism on the left) just shows... what? That adherents are too proud to admit mistakes and evolve?
It's true that in modern American/Western politics the term has a slightly different connotation, but to pretend that the idea of using data and knowledge to find good policies is new (which the OP claimed - millennials are the first generation to use data!) is silly. Smart people for centuries have been trying this approach and it's never caught on with the general public.
The fact that my original post got modded "funny" shows just how hard it is to get people to think seriously about this approach.
