Here are some good podcast episodes from Actually Existing Socialism that cover the GDR if you want a bit of an introduction:
East Germany: Stasi State or Socialist Paradise? w/Bruni de la Motte
The American Soldier Who Defected to East Germany (Part 1) w/ Victor Grossman
The American Soldier Who Defected to East Germany (Part 2) w/ Victor Grossman
What Has Socialism Ever Done For Women? w/ Julia Mead (This is a bit more tangential)
Writings available from the authors here:
Just to contribute to this point with something to reflect upon:
During the (laughably titled) “Red Vienna” era, when SocDems ran the city, the government built high quality housing blocks for the working people, which would house one tenth of the city’s entire population.
Rent in these blocks was around 4% of a working class income.
Are you pulling in more cash than a Viennese worker in the 1932, dollar-for-dollar (adjusted)? Probably.
Are you spending somewhere from 25-75% of your income on housing alone, making you effectively worse off than that Viennese worker in 1932? Again, probably.
When you crunch the rawest of numbers you can get some really skewed ideas about what the reality is. Statistics lie.
