I am probably the fiercest critic of the Bulgarian educational system since that I also decided to do my Master's degree abroad after studying for 16 years in Bulgaria. However, there are a couple of things that most people are missing...

First of all, going to study abroad gives you opportunities not only in terms of studies and work. In an open world like today's, when travelling is so easy, it's totally understandable that Bulgarian students would want to see other cultures.

Second, I don't agree that there are no opportunities for well-educated people in Bulgaria. I totally agree they are much less, it's much much harder to get them and there are a lot of problems everywhere. But all the people leaving is not going to solve the problem. That's why it's good that many foreign-educated Bulgarian students decide to come back and try to CREATE opportunities for themselves. One example are all the members of "Tuk-Tam" - "Tuk-Tam" - an NGO uniting Bulgarians, who studied and worked abroad, and who have returned or want to return to Bulgaria. (http://tuk-tam.bg/index.php?page=home&amp;hl=en_US)

Third, positive change is coming soon, I hope. On every level of the now terrible educational system. It's just inevitable. Another good start is the Bulgarian branch of the American "Teach for all" network (http://zaednovchas.bg/) which would send young teachers to the schools for a first year now.

P.S. But yes, sometimes it's highly discouraging when you see the situation here in Bulgaria. When the problem is obvious but nothing does anything about it or does not want to because this would make his life harder or less affluent. But giving up is definitely not an option... Check this article (I would have written the same thing a couple of years ago when I studied in the same programme). It's a good example of some of the daily and practical problems in higher education. Let alone the big picture.
