Bigger threat to Poland is joining the EU and losing the zloty to the Euro. Poland could easily become another Ireland or Greece who can't get out of their mess due to the fact they don't control their own currency. By losing control of their currency in a sense they lose their sovereignty. Compare Ireland's situation to Iceland. Iceland still has the Krona (sp?) and they are much better off.
Erm...Poland is already EU member and get's billions out of the common pot to help to get their infrastructure up to date.
And for the Euro, it wasn't the Euros fault that the PIGS screwed up, Poland could also easily join this part of the Eurozone which is flourishing and prospering under the Euro, it's on them!
Iceland is now asking for the EU as they got totally broke during the anglo-saxon-made credit crunch and banking crisis.

Irelands biggest export success for centuries had been their laborers as they never got anywhere.
They used the monetary help from the EU to develop to the "celtic tiger", but sadly that again was more like a bubble as seen in the US and UK.
Greece was always a basket case and they missed the chance to restructure their economy (even with the billions of EU money going south).
Nothing of which is the Euros fault and those basket cases had been basket cases before and will stay basket cases with their own currencies back.
(The only ones profiting from those basket cases getting out are those Euro-countries are those who have an actually working economy and are no longer forced to prop said basket cases up)
