A lot of people either forget, or never learned, that Poland was once one of the largest and most influential states in Europe.Yes it was long time ago, but the potential was always there. The real challenge was surviving the consequences of being caught between neighbors whose ideologies gave rise to two of the deadliest systems of the 20th century.
Then it seems our politicians stopped being pragmatic and started bringing up ideological issues more often, which divided the population, while IMO not doing nearly enough to promote further development of the economy.
So now we have a population split on ideological issues, while Poland and Croatia are overtaking us economy-wise. We have had every advantage (geographically at the crossroads of multiple trade routes, sea access, EU funds, hard-working population, didn't turn into a Russia-style oligarchy...) but mostly slept on it.
