Poland is an interesting case to watch for several reasons. First, it does not have any 'organic' classes and organic class interest - most social classes and political groups are the result of social engineering during the past fifty or so years. More importantly, Poland does not have the 'organic' urban classes - intelligentsia and skilled labor - that in Western countries formed the basis of left of the center politics. Until WW2, such 'organic urban' class were mainly the Jews - whereas other city dwellers were mostly displaced rural populations - either pauperized lesser nobility which formed petit bourgeoisie (usually right wing or reactionary), or landless peasants and agrarian workers - usually influenced by a mixture of populism and Catholicism rather than socialism or even left-of-center liberalism. The significant growth of the cities under communism (from less than 30% before WW2 to about 60% today or about 50% in cities 50,000 or larger) was mainly due to the influx of the latter. So the bottom line is that most of the urban population and urban classes are "socially-reengineered" noveau riche - upwardly mobile rural population that often brought the countryside within them - especially its populism and Catholicism.
Lacking any organic class interest - Polish politics is mainly machiavelian machinations of various interest groups and coteries sharing more or less the same class position - a mixture of petit bourgeoisie and the techno-managerial class - who adopt various political orientations from left to right as a matter of convenience and popular appeal, rather than expression of their class interests. Hence the bewildering mixture of mutually contradicting (by Western standards) political positions in party platforms - socialism and free-market liberalism, conservatism and welfare statism, nationalism and neo-liberalism, etc. This is basically like card players picking their hands from the deck - any arrangement is possible, there is no such as thing as an "internally inconsistent" hand, they only thing that matters is to have the winning in that particular round arrangement of cards on hand.
I thing in that respect Poland is a laboratory case of what politics has become or at least where it is heading to world wide - whereas in Western Europe that picture is still somewhat muddled by the traditional class influences that are mere labels, especially "labor." Most "left" parties either started playing that game and dumped their ideology altogether, or got stuck in the previous era, play the old battle cries like a broken record, and still have not figured out why nobody listens to them. Another point, most people profoundly dislike these machiavelian manipulations and political utilitarianism and look for alternatives. So far, the only ones offered to them are various variants of religious fundamentalism.
