Migration, immigration and ageing crisis in Europe

                    In case of donor countries, the push factors and profits for migrants and immigrants were analyzed below, but what made me wonder after watching the video by Dr. Patrick Dixon is that if European countries, due to the ageing crisis in Europe and the necessity for demographic increase pretend not to “see” and do not count the illegal immigrants arriving in their countries, because of the above mentioned benefits, why wouldn`t Moldovan and Ukrainian governments pretend not to “see” the outflow of the illegal work migrants from these countries,  again because of the well-known benefits (remittances, economic development through immigrants earning: construction of new houses in Chisinau, etc.)? In this case the answer why there is such a huge amount of illegal Moldovan and Ukrainian migrants in Europe would be quite clear and, knowing the corruption system and irresponsibility of Ukrainian and Moldovan border guards, this assumption sounds undeniable to me.   The question is how, given the presence of EUBAM in the border regions of Moldova and Ukraine, the illegal migration from the examined countries is getting higher and higher in numbers? In my opinion it is clear that illegal migration is profitable for both parties, which makes its tracing even more complicated because both parties are ignoring the fact.
