In particular, this bit:
"That their accent, speech patterns and knowledge of institutions, by their very deployment in the job market, perpetuate norms that exclude those who were born outside of the cultural elite."
It's a very valid point that culture drives so much of hiring and economic reality. That it creates economic barriers everywhere.
There's also a valid complaint against the meaninglessness of the office job. But to say "Hipsters :("... I'm not sure that really means all that much on its own.
I don't think it's a case of seeking meaning in a pointless non-struggle by emulating the struggling classes.
It's the same as it always was - the middle classes trying to differentiate themselves by social signaling - doing things others can't. Classic yuppies just bought expensive toys. The newer generation spends on other things. For instance, by dressing like a hipster, you can signal that you are not chained to the traditional office. You can buy $8 drinks at bars on weeknights. You can spend a year or two abroad.
We aren't quite like Effie, but only because the peacocking evolved in a different direction.
But let's not forget that Hunger Games is some ways an allusion to the Roman Empire - and that the fundamental problem is not a new one.
