In Eastern Europe communists tried very hard to erase cultural differences between classes and this left some lasting social consequences, which is why today there aren't such strong class distinctions in the way people speak.
This is actually a very interesting topic and explains some of the cultural and political differences between Western Europe and Eastern Europe today.
For example one of the things that communists did in Eastern Europe was that they tried to "mix" social classes together, like for example when they built those huge apartment blocks they deliberately housed people from various social backgrounds in there. Their ideal was to have workers, (former) peasants, bureaucrats, teachers, intellectuals etc. all living together in the same buildings, same neighborhoods. Communists also purged the old elites from power, so members of old elites would end up mixed with people of lower classes in this way.
One specific example of this I can think is years ago I was listening to an interview with the president of UEFA (governing body of European football) Aleksander ฤeferin, who is from Slovenia, and he revealed that his father was a prestigious lawyer but their neighbor was a cleaning lady, and their apartments were of exactly same size. This is what communists in Eastern Europe were pushing for, having people of (former) elite living next to working class.
Because of this, certain cultural differences between classes were erased, including the way people speak. People who grew up in the same city or region would develop the same accent regardless of their social background. There would be no accent associated with elite, because such cultural elite no longer existed, the communist officials who were the new "elite" generally came from lower classes. Of course educated people would generally have a richer vocabulary but they would still speak more or less the same as lower classes in terms of accent, pronunciation, intonation of words etc.
It's still like this today, in Eastern European countries (at least the ones I'm familiar with) you don't have anything equivalent to "posh accent" or Received Pronunciation or whatever it's called in Britain. In Britain this accent is associated with upper classes, especially in some exaggerated version, and few people in the country speak like this in daily life. It's not regional but related to specific class. In Eastern Europe, accents are regional, people from the same region speak the same regardless of their class. Of course there is a need to learn standard pronunciation of the national language for education purposes and to be better understood by people from other parts of the country, but this is not some snobbish class thing. Some rural dialects might be looked down upon, but those are regional differences, not class differences.
So yes, there are very few distinct class markers in Eastern Europe in terms of accent and the way people speak, especially in terms of their economic class background. I think this is largely due to communists aggressively purging the culture of upper classes.
The interesting thing is that the attempt of communists to erase cultural differences between classes had some completely unintended consequences. One could easily argue that this strengthened the sense of nationalism in the Eastern European countries, because it erased many distinctions between people within the same nation, and basically integrated the nation more strongly. Before communists took power, Eastern European countries still had many internal divisions, remnants of old ruling classes, different ethnic groups, large rural populations etc. But communists made these societies much more homogeneous in every way. So even though they were trying to build something completely different, they just ended up concluding 19th century nationalism, but in an even more radical way than it was done in Western Europe.
As a result of this, Eastern European countries are more nationalistic and socially conservative today, there simply isn't a strong enough upper class that would be associated with cosmopolitan liberalism. Ironically, the communists made Eastern Europe more "reactionary", as they would say, in the long term.
