I think Euro-socialism is what most of those kids want, whether they are aware of putting it in those terms or not. The culture wars seem to dictate that there are huge contingents of tankies among the youth, but that doesn't really seem to be the case on the ground (i.e. not on Twitter).
The DSA, the biggest, by far, left-org in the US appears, at least to me, to be pushing a platform indistinguishable from a Euro model.
