Regarding TPSA: Simple thought that instantly comes to mind is "Perhaps TPSA is a good solid business -- a golden duck -- so let us Treasury keep our shares in this golden business"? Why almost 50% of TPSA is owned by the French? For exactly the same reason!
TPSA can contribute to the state treasury in two possible ways - through taxes and through the dividend - I don't know the actual state of affairs (and I am not interested that much to investigate it) but keeping shares in a company makes sense (for the treasury) if there is some good dividend paid (and actually if we have influece on the amount of the dividend (I don't know if Polish state does but from what you write it does) it is good to keep it (but hey where the hell is liberalism)
now consider that Polish state gets rid of all the shares it has in the TPSA - it loses the dividend surely - but suddenly too it may appear that the tax collected from the company drops (for some book-keeping tricks - let's assume the income is "transferred abroad")
but still - where the hell is liberalism - or why keeping to the letter of liberalism may not always be the best thing (as to the letter of any doctrine - 'everything should be in private hands' is a doctrine)
that the positions in the Boards of Directors of companies like TPSA are political 'booties' is a different matter but still can be solved
not only by the state getting rid of its shares
I though the basic idea behind the bank was a difference in interest rates on money borrowed and lent? We have so many banks and they operate OK. Meaning the buyers for their services can be found?
don't you think they are hmm ripping the population off - and what about their income - are they investing it back in Polish economy or rather pumping it out to help their 'troubled' main branches - btw I'm pretty curious what is the typical credit rate in Western Europe as compared to Poland (find me a bank that will give you credit for less than 15 per cent)
