Really? I think you'll find quite a few fans up and down the country can't afford to attend football as often as they would like, perhaps your financial situation is more stable but a lot of people struggle to justify £500 per year costs. You're right though, nobody is forced to go but I suspect...
Say Bayern Munich were paying this much to Robben but were still charging fans realistic ticket prices and subsidising fan costs then it's kind of fair enough, when the costs to the fans are spiraling out of control then it's ludicrous. If that happened to us here at the Albion I'd be out.
