Economy was state-run, but things weren't so bad. However, it was due to purely political reasons: the Great Leader was taking loans from both sides of the Iron Curtain so that Yugoslavia wouldn't go bankrupt.
In order to enforce equality among different nations within the same state, they had to falsify history and language. In those areas, there were things you couldn't say in public unless you wanted to do time in jail and lose your job. It was actually called "verbal crime".
