Ticket Brokers exist because the tickets are being sold for less than what people believe they are worth. That's an economic activity, not a social one. We aren't talking about food, water, or gas in a disaster here - we're talking about luxury items.
If the tickets were sold at the clearing price, then ticket brokers would not exist.
I'm honestly curious - do you find Broadway's latest trend towards "variable pricing" anti-social? From the perspective of the customer, they are doing exactly what the broker's are doing - marking up the tickets to the highest possible price they can get on a per-seat basis - sometimes marking tickets up 2x to 3x what they used to be.
Obviously the producer's are happy with this - because they are now collecting the $$$ themselves. But, from the perspective of a customer - prices are now jacked up to what the market will bear.
I'm interested in your perspective - is the broker "anti-social" because they are depriving the producer of money, or because they are jacking up the prices of tickets to a level that the lower-income fan can't afford?
I'm sorry for you that you can't see how incredibly antisocial this is.
