PO could do very well
That's only for those who wish PO to do very well. The majority of Poles do not! They've had their fill of Platformerism.
Capitalism
Yes, but capitalism with a human face -- not a dog-eat-dog society, cut-throat competiton, the mindless ratrace and de-humanised hyper-commerialisaiton of ever field of human endavour. According to the RP Constitution Poland has a "social market economy", not capitlaism. That should be a kind of third road with room for higher things, a cultural mission, human interaction (being destroyed today by mega-gadgetarianism) and spiritual values.
get pregnant earlier
Did you know that biologically the ideal, optimum age of intial childbirth is 23. Younger and older than that entails increasing risks to mother and child. But such information is being suppressed today by feminists and other opinion-moulders. What is being promoted instead is greed, money madness and obsessive careerism.
Increasingly females want to first complete their education, start a career and often put child-bearing off to the biological limits of mid to late 30s. At that stage it is too late for another child. Not to mention those who, swayed by all the glamourising singlehood propaganda, eschew maternity altogether. And we have the source of the demographic crisis.
if it was discovered
That kind of speculation can apply to anyone... What would happen if it was discovered that Tusk was a wife-beater and Komorowski a secret transvestite...
Moczulski of KPN, despite his nationalistic rhetoric, had indeed been a communist collaborator. Kwaśniewski had been in the communist apparatus and the others from Nocna zmiana all had some form of political collaboration on their conscience. The fault lies mainly with Wałęsa, although probably his actual guilt was the smallest. Sure he signed some pledge to play ball with the regime but never did. His failing was a purely human one: an ordinary worker buoyed into prominence by history, a Nobel laureate and the President of Poland sudddenly felt threatened and panicked.
Had he allowed the lustration process to take its course, there would have been 1-2 years of commotion and things would have got sorted out. None of the other Nocna zmiana anti-heroes had the clout, either singly or collectivley, to oppose lustration if Wałęsa had not organised such a backroom coup.
