Many aspects of the post-communist economy were shock to the society, for example sharp rise of prices on food that was previously officially sold at small, regulated prices even though it was in fact rarely seen in shops. Many state-owned enterprises and collective farms were already insolvent in 80's and didn't pay their workers for months or years (which was the cause for unrest) but from legal point of view they weren't bankrupt, since the concept of bankruptsy of a state-owned enterprise did not even exist in the communist legislation for ideological reasons, just as didn't unemployment.
