We can only answer this question based on our own personal experience and observations. We don't pretend to have completed a thorough sociological study of this problem; however, we do speak from our close relationship with Romanian workers who see the problem every day.
Child abandonment in Romania has been a problem for decades, although it only came to the world's (and the average Romanian's) attention after the fall of Communist dictator Nicolae Ceausescu. Ceausescu's brutal regime did much to create the conditions which have led to so many children being abandoned.
Most observers will mention that Ceausescu's regime, besides creating widespread poverty, fear, and ignorance, also outlawed birth control and abortion. And indeed, the illegality of birth control certainly contributed to the problem among the needy people of Romania, especially the impoverished Gypsy population. However, we believe that it is absolutely faulty to suggest that legalized abortion is the solution to child abandonment. Abortion and birth control have been legal in Romania for over a decade now (in fact, Romania has one of the highest abortion rates in Europe), and yet the epidemic of child abandonment continues unabated.
We believe that the problem of child abandonment is caused by a number of factors, chiefly poverty and ignorance. But the main cause, we feel, is the mentality that human life is disposable. Ceausescu certainly perpetuated this mentality, and it continues today. Abortion, far from being a solution, is merely a more brutal form of this same mentality. Our hope and prayer for Romania is not only that poverty and ignorance will be alleviated, but also that a newfound reverence for human life will prevail. Then, we believe, the situation of Romania's children will dramatically improve.
