Apart from maybe playoff tickets, I don't see much evidence of it in American sports. At least round here, the economy is such that the New York baseball and football teams have had to reduce ticket prices across the board. They built fancy new stadiums and tried to hike their prices, but crowds dropped off.
When I first moved over here, there was 10 year waiting list to get New York Jets season tickets (and they were even worse then than they are now). The list was closed.They have burned through that list the past couple of years to the extent that they are advertising season tickets for sale on the telly. Not only that, but they have a whole load of tickets for sale at $50 a pop.
Similarly, the Yankees were in a battle for the pennant a couple of weeks ago and yet on Stub Hub you could pick up tickets for many of their games for less than $10. One game they were offering $4 tickets.
