The only reason the Netherlands isn't doing very well is because we're trying to lower our debt. People have less to spend and thus the economy goes down as well. We wouldn't have so much debt (and thus no reason to lower it on such a short term) if we didn't pay Greece.
So yeah, Greece is quite directly influencing our economy. Thank you Greece and thank you France for convincing the rest to let Greece join in the first place.
Edit: Besides, it's illegal for EU countries to lend eachother financial aid. But I don't think anyone willing to sue the EU is going to win.
