I am French but travelled extensively to Poalnd and lived there for some time. This is a truly wonderful country.
The one thing that is a insurmontable barrier to go and live there (I considered that) is the healthcare sstem. It is completely broken.
You have free healthcare where people behave like beggars in front of the demi-god MD. They do not pay him for hs work, officially, but there is money slipped under he table to make things work. It is unbereable.
Then you have provate health care whichis not not bad, until you have a serious problem and you are back to the public system.
Finally the medicines/drugs are not refunded. You have to pay for them. This is wild for someone coming from France.
I think that if Poland upgraded that part of its politics it would be a country bringing in lots and lots of people useful for the country.
