Moving from socialism to capitalism greatly improved Poland's economy

See Poland’s Economy Set to Enter Global Top 20 Following Another Strong Year by Don Nico Forbes of The WSJ. Excerpt:

"Poland’s economy topped $1 trillion last year, punctuating a decades-long boom that is in stark contrast to the faltering economies of its much bigger European neighbors.

The milestone, confirmed by data released Friday by the country’s statistics agency, likely lifted Poland into the world’s top 20 economies for 2025. It is expected to supplant Switzerland, which hasn’t yet released its end-of-year tally. Poland now sits right behind No. 19 Saudi Arabia’s $1.3 trillion economy.

Three-and-a-half decades ago, under an isolated communist regime, the purchasing power of an average Pole—adjusted for local prices—was on par with Jamaica. Now, it’s higher than Japan."
