Freedom of movement is still restricted. The only ones to have travelled freely have been the criminals. Crime is international. It involves massive, intricate and sophisticated operations of export and import, knowledge of languages, an acquaintance with world prices and the international financial system, demand and supply in various markets, frequent business negotiations with foreigners and so on. Such a profile and itinerary would fit those of any modern businessman.
Criminals are, after all, international businessmen.
Their connections abroad, coupled with their connections to the elites in their home country and compounded by their financial prowess have made them the first and only true businessmen of the economies in transition. There was no one else qualified to assume this role, and the criminals stepped in willingly. It will take one or more generations to replace them with a more civilised breed of entrepreneur. In the 19th century, the then expanding US went through a similar process. Robber barons seized economic opportunities in the Wild East, West and everywhere in between.
