I have no issue with your definitions of what is elite and non elite, but frankly you're making the wrong contrast from the outset. The division should be financially doped v sustainable. City/Real/PSG are based on huge investment that will never be paid back and has endless resource until that well is emptied - United/Woolwich/Us are sustainable, we exist in a world where we have to balance the books.
The minute you see it this way everything we're doing makes sense, if you want to retain players or grow sustainably, you need a bigger stadium because that will increase the income stream and therefore improve the club's ability to retain talent. If you want to be very hard nosed about it, the player that Real would have paid £100m for is now £200m because our ability to say no to an offer has increased because we have created more sustainable wealth, that's not madness or unambitious, it's giving the club a more stable long term platform.
Taking off the hardheaded side of things the new stadium is a fantastically good thing too, as someone who was on a waiting list for 14 years for a season ticket, I felt denied when it came to seeing Spurs regularly, a lot of fans who wanted to get to see Spurs were not limited by ticket price but sheer availability. I won't say I'm a fan of Wembley but one thing's for sure, it democratised our fan base, those who want to see Spurs have got to see them and the new stadium gives that opportunity to more of our fans every game, the pricing will be a contentious issue and may see fallout but if you are not excited about being in the new White Hart Lane with 59000 other Spurs fans cheering the team on, I question why you want to follow this club.
Finally, I think your main argument is that the board are prioritising the money over the glory, the runs in the CL and PL over the FA Cup and the League Cup. No one here wants Spurs out of the cups but the reality is that they are not what they once were, we won the League Cup in 2008, it wasn't a platform that led to the Premier League. Woolwich won the FA Cup and had their parade and yet they knew that the cup was a piece of paper barely covering a crack. If we win the FA Cup I'll be on the high road cheering the bus past. The fact remains, retaining a place in the champions league will make us more sustainable, will allow us to retain more talent and more for the club in terms of prestige and money than an FA Cup ever could. It's not a situation that makes me happy but it is the reality that we're faced with.
When you look at the way the club is managed, the goals set, the fact we are fighting on 3 fronts pretty fucking well, I struggle to see how you can be too critical of ENIC, aside from the very salient points that the Trust have pointed out.
