So you really did mean to use the word antisocial.
Bugger, you got there before me.
"Surviving" is easy. We all know Metalheads in their twenties, thirties, and possibly even forties, who have secure (shit) jobs which will last them until they retire. A number of these probably play in a band or two, on the side, as an expression of their love for the music.
"Progressing", on the other hand, seems to be far more difficult for the average "Metalhead". That guy in his twenties playing local Death Metal gigs every month while he makes his money picking up rubbish in the mornings is going to end up being a guy in his forties playing local Death Metal gigs every month while he makes money picking up rubbish in the mornings (though he might have managed to procure a steady girlfriend/wife and child[ren] by then).
It's not a glamorous life, by any means, but I can accept that it could be considered to be pretty damn good for somebody with the intelligence to deny this broken society and a passion for our music/aesthetic. I'm not looking to make millions in the city, or to pave my way to stardom with derivative crowd-pleasing "Metal", and I suppose that having a physically stimulating job, a good family, and a kick-ass band in which to play would allow me to enjoy and explore life at a comfortable, easy pace, but it's not challenging in the slightest, and leads us all absolutely bloody nowhere except right back where we've been since the '80s (or worse, depending on your perspective of the decline of modernity).
Hessians need to do more than "survive": we need to coalesce and raise our culture into the real world, instead of keeping it locked in the human world of ideas, dreams, and rubbish collection.
