You have no clue what you are talking about. I wonder why this sort of obnoxious reasoning always comes from Poles and never from Czech people for example.
Yes they do.
> And they are still benefiting from slave labor
Not sure whether that really matters now-a-days for the economy.
> stolen precious metals
One of the cores of industrial and mine centers that made the German Empire thrive during the Belle Epoque, are now owned by Poland.
> Not to mention the Marshall Plan.
Half of Germany, didn't got to get it but where instead paying reparations for whole Germany. Sorry, I'm a bit tired of acting like Germany only got the history of being on the west side of the iron curtain. It got both treatments.
Well glass that has half of water is still better that glass fully empty. Poland didn't get any war reparations and after being more destroyed during the war than germany (warsaw burned to the ground) and pretty much occupied for many decades after the war then how polish companies supposed to compete with any western economy including germany?
