As lower middle class hippie, who is on the poor end of even that and was born and live in an area that's known for hippie types, I strongly dislike most of those upper middle class "hippies". For most of them it's fully a surface level thing and they are a big part of many negative views people have about modern hippies. And it's always so fucking funny when a group of them go to where actual leftist hippie types hang, bars or whatever and think they don't stick out like a sore thumb. They walk in looking like shitty parodies and act exactly the same as the snobby people who are strongly disliked there. I've even seen some who does the whole keeping the price tag on thing like that's something that wouldn't be laughed at.

For some reason I take it to mean more of an airhead type hippie who's irrationally averse to "chemicals" in everything and talks about the vibrations of the universe.

Those types are what me and my wife like to call "neo-hippies," or "bobos," to borrow from French.
