certainly policy-wise there's been a kind of centre-right monopoly since the dawn of New Labour - the socialist left was pretty much dead until Corbyn's takeover. There's certainly a few things we could do with from a stronger left vision - primarily returning the NHS to its former glory, instead of leaving it to wither on the vine like successive PMs have been doing.

Irritatingly enough, in my experience millennial progressives don't seem to care about actual valuable socialist policies but more about shutting down open debate with misguided accusations of various forms of bigotry. Policy-wise the best I've seen is calls to elect whoever the most left-signalling person is regardless of their policies or character. I'm sure that's not the majority of left-leaning 20-30 somethings but it's certainly a majority (perhaps 70%) of those I've interacted with. Not that it's a problem that's isolated on the left - the right has been getting more conspiratorial and detached from reality too. It doesn't give me a lot of hope when debate moves from open discussion of policy to shouting slurs across the aisle. It just serves to harm meaningful movement on policies that actually might make a difference in people's lives. Even Brexit rapidly devolved into "the people who hate Europe/immigrants vs the people who are afraid of change/are naive". I think until the gap is bridged, policies will continue to change (or not) without my generation taking any notice whatsoever.
