I always figured there would be a market for a consultancy which would go over your family history and tell you where you qualified for bloodline citizenship, or other similar accomodations.
For example, ISTR Germany had special programnes for descendants of people displaced by their genocides, and won't Italy take people with ancestors several generations back?
Surprising you don't see countries courting a "self-deportation" market too-- your local government doesn't like you for social/political reasons? We'll be happy to accept your skills and economic potential!
