So promoters are colluding with themselves to under price their product, so people unrelated to them can capture the profits more rightly due to the prompters themselves? You sure about that? If, as another poster claimed, it's regulation that keeps face value artificially low, that's not anti-trust. That's government trampling property rights, and distorting markets.
I can see that we’ll never agree. What happens is that a lot of bands refuse to gouge their fans and contractually demand that promoters sell certain seats at a price that they believe is affordable to that fan base. Scalpers are a monkey wrench in that mix, and while you might be appalled, I’m always happy to see security hand out the liberated tickets (they do) as the police lead the scalper away in cuffs. What’s a cherry on top is that I haven’t heard of a lawyer yet who’s willing to challenge the impromptu confiscation in court. IMHO, the scalper deserves the humiliation.
