I don't think most have a serious position worth considering. I say this as someone lumped in this demographic whipping boy.
There is plenty to be legitimately angry about too. I just don't trust this generation to come up with solutions that aren't literally "let's try real communism. This time it will work!"
What makes you feel this generation would go that far? I haven't seen anything that's led me to believe they think this way, in my understanding, they are more aware of and accepting of fundamentally "socialist" concepts such as government assistance and high-taxation. That's a far cry from communism.
Also, there are large and loud political movements pushing for Scandinavian-style democratic socialism which has been successful, it's simply dismissive to act like all millennials don't understand politics and are just trying to be edgy.
The United States government is coming out of a month-long shutdown because the idea with political traction (the big, beautiful wall) was completely unworkable.
Let's not underestimate what flies and doesn't fly in the arena of American political thought.
