We are already bottom of the lists in most EU countries, when it comes to big projects, the French in particular interpret EU single market rules and subsidies in their own unique way,

(not to their country's disadvantage, it case you hadn't noticed

) so what is going to change?

EUSSR is a busted flush, it is just a question of when it implodes as they had not carried the electorate along with them, in much the same way as the USSR. You can get away with this to a degree if the population are financially comfortable and happy, but as living standards fall dramatically over the next 10 years in Europe (including the UK) and the PIIGS have every more unrealistic austerity measures applied by
Germany the EU under this new stability pact, it will result in major uprisings in many EU countries.

The old financial stability rules of under 3% deficits and less then 60% debt to GDP have been with the EU since the ERM days with fines of up to 2% of GDP, why was it not imposed to stop what has happened now? Because virtually all of the Eurozone countries haven't and don't comply, it was effectively dropped when Germany and France broke the rules and told the EU that you are not going to fine us.

So having even tougher rules is a joke, 0.5% budget deficit and max 60% debt which France doesn't meet 82% debt to GDP and 4.5% deficit and Germany doesn't either with 1% deficit and 83% debt.
In reality all they are doing is trying to flatter and convince the markets that the EU finances will improve (they won't) to convince the markets to support the Euro to stop it failing (they won't) and to try to make it look like the EU politicians have now got a grip on the crisis (they haven't).
The new rules were deliberately setup and imposed by the French and Germans to make the UK use it veto. Why? So all of the headlines for the next few days (France and Germany hope for the next few weeks and months) is on the UK's relationship with the EU and not on the failing Euro. I expect the markets will have woken up to this by at the latest midday Monday.

For those of you that like a good Brian Rix farce, here is the EU statement on the new rules. The opening paragraph is a good joke in its own right.
