1) A lot of polish people (and I mean A LOT) work abroad... as Poland don't tax these, they don't show up in statistics. Poland is probably higher up in the rank than those statistics show. Sure, it's not Scandinavia (or the nordic countries, sorry mr Warmbold) or Germany but it is still better off than a lot of the other countries on that list.
2) I think we are being unfair with Kubica. He has won a couple of stages this and last year. Sure, lately he has lost pace which is a shame. I hope he has the ability to regain it. His ultimate lack of experience is hampering him but I don't think he can blame that forever.
