I will outline the Bulgarian perspective of events.
By the mid 1980s, "perestroychiks" in the Bulgarian communist party had prevailed over the old generation of die-hard communists. Despite officially calling themselves "communists", these people were avid pro-westerners and believers in market economy. One such key figure in Bulgaria was Andrey Lukanov, a minister of foreign trade during that time. When the Berlin wall fell, he headed the first democratic government and remained an influential force until his murdering in 1996.
Andrey Lukanov spoke eloquent English and was actively seeking economic ties and advices from the US. He even went so far to ask two American economy professors to devise a detailed economic plan which would guarantee the optimal transition to a market economy. Even the long-time president and communist dictator Todor Zhivkov officially admitted during his final resignation speech in 1989 that "communism was ill-conceived and we must be welcoming all foreign western capital". The trouble is, western capital didn't come as quickly as expected. We were left with factories and enterprises which were unable to compete with their western counterparts and our market was quickly flooded mostly with foreign goods. Everything else follows from this.
The privatisation therefore was more of an emergent act of saving the failed state enterprises. They were sold for pennies because they couldn't export their production and the domestic market was dire.
Nowadays, we have tens of US-backed NGOs (most notably "Otvoreno Obshtestvo", America for Bulgaria Foundation, Bulgarian Helsinki Committee, etc.) which work very hard to persuade us that gay rights, minority rights and saving the polar bears are the most important problems on our agenda, without ever acknowledging the deep economic problems that cause social tension and emigration.
