If you'd really like them to come down, then why criticise people who are trying to achieve that? Because next season, it might not be £50 for you and your son but £70.
So why kick up a fuss now? Because there is more focus on ticket prices generally this season is probably the main reason and the battles are being won. Another reason is that people at the club have sat down and thought hard about how to set prices at a level which maximises income, rather than at a level that maximises attendance. They are presumably prepared to accept an number of empty seats for the sake of screwing a few extra quid out of us.
