Are business and commerce separate from a subculture?

I was thinking about this topic from something mentioned during Tuesday's discussion. Particularly with the punk subculture in mind, must subcultures be separate from business minded agendas? I've decided for myself that it's not so black and white. It seems as subcultures gain some notoriety from the general public in a capitalist society businesses want to profit off of that.

Youth are an especially big target for new clothing and it makes sense in McLaren's case that he wanted a vehicle to promote his style of clothing. I wouldn't say that this choice alone is one that pushed punk into the mainstream though. The mainstream acceptance of punk that would follow was a by-product of McLaren's efforts through the musical success of the Sex Pistols. In other words, the Sex Pistols' success is what brought punk to a larger audience not simply the attempt to sell punk clothing. Therefore it is surely possible for youth cultures and businesses to interact without that subculture losing its integrity however due to the nature of attempts by businesses to promote themselves sometimes it is hard to avoid.
