enforce further austerity
Hm... in general austerity would seem to be the right approach when we deal with a state near bankruptcy, but it is somewhat debatable whether the Greeks should be pushed further. They have already made a lot of sacrifice and more austerity measures might be counterproductive.
Greece in general is an interesting country - knee deep in debt ever since regaining their independence, and not exactly by their own fault (Greek history is quite complicated in this respect). I can only wonder what the Greeks (a very resourceful nation) could achieve without the iron ball of debt constantly chained to their ankles.
agree it's too soon to judge
The article suggests that British economy will flourish in the coming decade. If they're right, it will definitely reinforce euro-scepticism in many EU countries.
I don't believe Poland will leave until it starts being a net contributor to the EU
What Poland fears the most is isolation. Too many times in our history we had to face mortal danger alone with enemies all around us. That's why so many Poles appreciate the safety and stability that EU brings (and we are finally pals with the Germans - that has to count for something! :)). Even if Poland becomes a net contributor to the EU budget (and one day she will), there's not a snowball's chance in hell we'll want to leave the Union.
