Oh, yes, agreed, but take a look at the article - it is damning - and it makes some very good points, including some of the ones you have made - and more.
As usual, there are several culprits - planners, Olympic requirements, greed of football clubs (Karren Brady gets a mention), politicians (our friend, the former Mayor of London, currently serving as Foreign Secretary), bureaucrats; it is a most interesting and well written piece, and worth thinking about.
Anyway, I recommend that you read it, as you are a West Ham fan; indeed, I think everyone should take a look at it.
