I was just comparing the average GDR house, to a modern one. It's not that different, and most people lived in an apartment then as they do now. Both are similar in quality & abundance to housing in West Germany, UK, etc.
Contrast this to manufactured goods. Eastern bloc residents couldn't get a car, and if they did it sucked. They couldn't get enough razors, toilet paper, car tyres. All the things that were abundant and cheap in the west, and are abundant and cheap in those countries now.
We can argue about the small/marginal differences in quality or abundance of housing under different systems. We can't argue about the massive quality & abundance differences for industrial goods.
This is why I'm quite leery of ideological "theory." From Marx to Rand, it all seems too grand to me. At the end of the day, these were economic policies and their successes and failures varied.
