I don't think you can call New Wave musicians hippies, considering that musical movement is an offshoot of another movement (punk) that was in opposition to the Hippies.

However, middle aged people have some pretty specific brainworms that are most commonly encountered around that demographic, such as a fixation on stuff being "natural", "fuck you I won't do what you tell me" + a proneness to conspiracy theories + being from teenagers to around 30 years old during the fall of the USSR and the new age boom of the 90s = willingness to believe reactionary rhetoric while having absorbed a lot of anticommunism.

Older people's reactionary views are usually some kind of religious shenanigans, while the youth's is a meme-soaked culture of "treats are in danger".

Even in spite of all that, ultimately it all depends on one's material conditions. A 52 year old woman with an interest in ufology, who thinks the best medicine for cancer is homeopathy and is casually racist against the Turks she sees on the streets is still likely to be on the side of the union if there is a labor dispute at the workplace she is employed at and support a left wing party while a 26 year old college educated homosexual who grew up in a progressive household and had parents in the Communist Party of [x] might not, if they are in a higher paid position at the same workplace and then go out and vote for neoliberals like the Green Party.

Of course, there's layers to this, as always. False consciousness, the effect of being labor aristocrats, opportunists trying to pander to conservatism and the like.
