The point still stands. Sunderland have a passionate fan base from the city and the surrounding areas.
If we are to become a solid top 10 premier league club or higher we need to grow our revenue
We can either ask the same people who already spend money on Sunderland to spend more, or we can find new people who don't already spend money on Sunderland and persuade them to start spending money.
There is a finite limit to how much you can squeeze more money out of the same set of supporters until it gets to the point where it is unfair. People might not like changes to accomodate new comers or corporate customers, but the alternative is that we all spend more
Which do you want?
I have no problem with us extending corporate facilities and also attracting "tourist" fans too watch us, I don't think either is a bad thing at all, as long as this doesn't impact and drive out our core base of fans. The club needs to serve both groups, and also needs to be aware that if the football side becomes less successful only one of those groups will remain.
If they get too obsessed with the corporate side I can ultimately see that being damaging, especially given our geographical location - we are never going to attract the volume that clubs in London/Manchester/Liverpool/Birmingham can in the same way that we don't attract industry headquarters/head offices to the area.
