What unintended consequences did the perestroika have?

One unintended consequence of perestroika was the rise of organized crime and corruption as state controls weakened. Another consequence was the rapid economic decline and social upheaval that followed due to the sudden dismantling of the centralized Soviet system without adequate planning for a transition to a market economy. Additionally, perestroika contributed to nationalist movements within the Soviet republics which eventually led to the dissolution of the Soviet Union.
