There is a useful page on a political movement under the name "Progressivism" at this link. The various sub-pages are, unusually, at the bottom of the page. As I read it, this is a Naderite movement, vaguely equivalent to the ideal (but not the actual) Green Party in Canada. I say not actual because the party platform of the Greens is manifestly feeble relative to this American version.
For contemporary Degeneracy, see Marilyn Manson's Nachtkabarett and its "Degenerate Art" section.
