A proverbial can of worms would also be opened up with regard to many propertied families in the former German Democratic Republic and in western Poland, whose properties were expropriated. While it makes for genuinely poignant family history, for people with titles linked to land in Poland especially can imply a calling into question of the Oder-Neisse border between Germany and Poland.
When one speaks therefore of dynastic restitution of properties east of the former Iron Curtain, it is somewhat reminiscent of the situation of the post-Sandinista government in Nicaragua, when huge US companies incessantly demanded compensation for property in pre-Sandniista times to the extent of it becoming US foreign policy. (All the Sandinistas had to do was to say to the poverty-stricken Nicaraguan electorate: 'Look how the US is treating the government that is supposed to be its friend'; the Sandinistas were later elected to power: with an aura of legitimacy which the incessant demands for restitution by big corporations had ironically given them.)
If formerly reigning dynasties in parts of Eastern Europe ever hope to become established as popular and representative, then concern for the welfare of the common people needs to be a stance that is put way before issues of dynastic property restitution.
