- it was kind of inevitable once Poland stopped being oppressed by its neighbors. The USSR, Nazi Germany, the German Empire / Prussia, Austria, Imperial Russia, etc. have basically been dividing the country since the 1780s. Without these restrictions, Poland is a natural leader in its region purely on population alone.

- A general lack of ideological “mind viruses” that seem to plague the western world. Most Poles are pretty straightforward, common sense people. They might have opinions you don’t agree with but it’s not a country of extremists in any direction.

- the general openness to American culture and (over)work ethics. I think Poland probably looks more to America than it does any EU country, although this of course isn’t simple, especially lately. But in general it’s a pretty hardworking, business-open culture. My impression is that it’s much easier to operate a business here than say, Germany, Italy, or France.

- Something I need to read more about, but IIRC Poland dealt with its oligarch problems in a different way than Russia or Ukraine did post-USSR and so doesn’t really have this issue.
