A lot of people defending City on this are changing their parameters as time goes on.
None of those claiming that you have to weigh it against the quality of football on offer (i.e. good football, I will be willing to pay a lot more) care to answer whether they held that view when City were shit - yet charging the highest prices in the lower divisions - and therefore fucked City off because they were not meeting the success/cost criteria. They won't answer this because the logical conclusion of this is that they will fuck City off if the standard of football isn't good enough and they know what type of supporter that makes them look like (and I suspect a lot of them know they wouldn't/didn't fuck City off and therefore it makes a mockery of their cost/success analysis).
Another bizarre change of view, that has only been taken on by some in recent years is the analysis of how a 19th of a season ticket is the way to determine good value.
A season ticket has always been a trade off between club and fan. The fan guarantees attendance, the club, in return, reduces somewhat the amount that is paid for entrance to the game. Therefore, 1/19th of a season ticket has never, in any way, represented the normal price of a ticket.
Yet now we have people claiming that 30 odd quid, 1/19th of their season ticket, represents, just about, a fair price of a one off ticket, therefore season tickets are good value. But they are confusing two different things. They are comparing 1/19th of a season ticket as if it is the price of a single match ticket. It isn't! It is, and should be treated as, a significantly discounted match ticket. Therefore, all this "I think £35 quid for a match is fine" is absolutely irrelevant if you are talking about 1/19th of your season ticket.
If you are judging the price of a season ticket, judge it as it has always been, for 50 years. 1/19th of a season ticket is a heavily discounted match day ticket. So when you discuss your "1/19th of my season ticket is £35 and that is just about ok for entrance to a match" know that what you are really saying is that "£35 is a heavily discounted match day ticket price and therefore, I think that the normal price - significantly more than £35 - is fair and the correct way to treat fans"
