Are the people themselves complaining as they are in Russia? I doubt they'd ever want to go back to communism or that they long for the good old days of one party bosses calling the shots.
People are not complaining as much but we should notice that Russian “shock therapy” was really terrible. However majority of Poles negatively consider whole transformation process, they remember corruption, rigged every single privatization and the fact that communists not only were not punished but also preserved a lot of influence in the country. Nobody else but communists gained the most financially.
