Communism ended in Poland 35 years ago (1989). That's one or two generations ago.

That's long enough for everyone aged about 50 in 1989 to have aged out of the system.

How many decades should pass before we stop blaming present circumstances on the past?

It takes time to create an economy. Even with consistent 5% yoy growth that's a few decades to catch up when you're starting with a few times less GDP per capita.
