You could ask "Why does England continue to subsidise Scotland to the level they do, when all they do is moan about every last little ******* thing? They're all for seperation, why not give it and watch them sink entirely without a trace before they drag us under?" - I wouldn't ask that, of course.
A global event which attracts interest from every corner of the globe is a great idea, bring on the World Cup afterwards and anything else going - why not? You won't be paying for it for years, it'll be barely noticeable to you and if it hadnt been mentioned you wouldnt have noticed it at all, I suspect. It will provide focus for development in an area that needs it, provide targets for our youth and aspiring sportsmen and women, provide recognition for the sports arena, clubs and societies... it is the stuff of the memories of our old age... what is not to like about it?
Oh, ffs, Londoners will of course benefit most form the games, but they will also be paying most for the games... the games themselves will not be held purely in London and to think anyone coming from abroad is going to spend money here that will stay purely in London is a very naive thing to think. Furthermore, London does happen to support the rest of the UK to a massive extent (like it or not, its true!) so to support it in this time isnt a bad thing frankly. I don't live in London, far from it.
If its the price which really bothers you, how much do our little "peace-keeping" forays around the world cost? How many euro-fighters would the Olympics pay for? Here you go... http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/11/24/ndefence124.xml that should put the £10 billion for the Olympics into perspective a little shouldnt it? http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/11/22/nolympic22.xml
These are both taken from the Telegraph, about the most anti-government source (even though the government has little to do with the Olympics, I understand a lot of you seem to think they are the source of everything bad in this country) I could think of... so should provide a fair bit of balance on it!
