Again, this trend (corrupt practice) goes back to Tagliabue. Just like intitutionalized gambling.
My guess is that the Organized Scalping Organization(s) pays a dividend in addition to actual ticket price back to the league/stadium owner in some form or another.
Stadium owner, following a corrupted scale of reduced actual supply to actual demand, charges more per ticket to the non-syndicated fan.
That's the way it works in medicine. A drug that I need cost $160 one year; price jumped to $1,600 the next year. I asked a pharma-connected why. Answer: Kickbacks.
Reason? When prescriptions became significant. the drug manufacturer made a deal witInsurer and pharma split the 90% price increase. If you're uninsured, you bleed.
Moral (or lesson) of the story: Where prices or availability goes out of sight, look for kickbacks. NFL is a monopoly. An uncorrupt federal government could bust it.
