For that, someone had to pay, innocent or not. That's why the Lviv pogroms happened and maybe Jedwabne.
In contrast, I have the impression that the intelligentsia, the wealthiest Jews and those of the highest level of culture [with, of course, certain exceptions and not counting the pretenders], rather think of Poland often with a certain fondness and would happily greet a change in the present situation [leadingfhead to] the independence of Poland.
Of course, a certain calculation of self-interest is involved in this. At present they too are experiencing many hardships, if not collective liquidation - their houses are being confiscated, and their stores, businesses, and factories are being taken away under the muse of so-called "socialization" and turned into something like cooperatives [in which the participation of the state and the performance of services on behalf of the state occupy an extraordinarily large portion]. This makes it impossible for them to earn a living, even often to maintain a subsistence level. On the other hand there prevails among them in general the fairly deeply-rooted conviction that the future Poland will be a democratic state which will owe much to, among others, international Jewry - in part it will be dependent upon it - and so the Jews will not be persecuted.
Finally, there is no doubt that their Polish patriotism also plays a certain role, though it is difficult to say to what extent.
