The same is true all over Europe. Workers rarely lived in those buildings. Look to London for example, and the beautiful town-houses in the centre were built for the rich. The run down brutalist tower blocks and vast expanses of terraced housing surrounding the centre were what was built as there was a need to house workers within reach of the city.
You don't see the worker housing from before, because it's been torn down, or because the people in question didn't live in towns, but what was there was even worse.
The buildings in the quarter where my great aunt grew up in in Oslo is in a museum, as the last example of the awful conditions the working class lived in back then. The replacement was a brutalist tower block that certainly looks atrocious compared to the lovely early 1900's city blocks that remain in Oslo.
But those city blocks that remain are where the rich people lived.
