This is a pet peeve of mine because the 'millennial' label seems to be modelled on what are (at least currently) working class children of upper middle class parents.

The entire trope is 'well off kid ends up working in coffee shop whilst subsidised by mum and will never buy a home'.

It's a strange microcosm.

People like me that have solidly working class backgrounds yet haven't been abject failures just completely disappear in this worldview.

I guess that's just identity politics. At this point, trying to engage meaningfully seems like a waste of time to me.
