I think football on the whole is too expensive, but agree that cutting admission prices unilaterally would unfortunately be suicide.
It's a catch 22 on a major scale.
The SPL as a whole need to share more of the football income. Work on initiatives together that will broaden the viewabilty and sellability of the game - joint initiatives and investment on playing surfaces. Increasing gates on TV games. Getting back to having healthy away supports to add to atmosphere etc etc.
These are all pipe dreams tho.
I think there's a point on both sides of the argument. Yip, football is too expensive (for the regular dude going to a game) but there's not a thing to be done to reverse it any time soon
