That is how all economies grow. It is unnecessary to remove credit from Poland. You say labor is educated, for example. Is that also not their merit?

Didnt USA benefit from mostly not being bombed during ww2? Didnt Germany benefit from cheap Russian gas and educated immigrants after 2008 crisis in EU? In the end, we can keep going back looking for pthers to thank but the country did it, and it is fair to say so.

P.S. I also live in Poland, not Polish. I also lived in Berlin, and I dont think the salaries are always so different.
