ENIC won't be taking on debt to pay for the new stadium. THFC will. Therefore, it is only right and natural that THFC is responsible for repayments.
They're completely different scenarios. I'm surprised that I have to explain it to you.
Glazer, Gillette and Hicks placed huge debt on Man Utd and Liverpool without adding anything of value to those clubs. They simply bled them dry, to the tune of ?ú60 million and ?ú40 million per annum respectively. The clubs had nothing to show for it.
By going ahead with the stadium, ENIC will also be placing huge debt on THFC. But.......and it's a big BUT.......the club will only be taking on the debt to add massive value. The debt will pay for a huge asset. So Spurs' net asset position will be even better once the stadium has been built than it is now. The new asset will generate sufficient revenue to cover the interest and debt repayments while still increasing the club's profits by a significant margin.
So far from being entirely parasitical, as Hicks and Gillette's debt was to Liverpool and Glazer's debt is to Man Utd, Spurs' stadium debt will be hugely beneficial.
It might be a good thing if the club was owned by the fans. But, then again, it might not. You don't have to look too closely at this forum to find bickering, recklessness, ignorance, prejudice, chaotic thinking and downright stupidity. Nor do you have to look too deeply into the history of elections around the world to find electorates that have made giant mistakes and lived to regret it. Democracy can be overrated and isn't always the best or most effective solution.
As to your Trust fund idea, the point is that you would still have sold the club. Which would mean that the fans no longer had control. Which would mean that whatever money the fans donated to the club from the proceeds of the sale would, effectively, be giving the new owners back the money they paid.
