Well, their politicians rigged the books to get into the treaties in the first place. Things won't be so catastrophic for them (as they weren't for anyone else in 2008-2009) if they didn't report lies on their financial well-being to get accepted. Why doesn't thing go bad for Poland? Or Czech Republic? Because their finances are solid, not based on vaporware, and they don't lie to the world and themselves to get short-term benefits. And they actually work.
