So what's the question if you aren't talking about revolutionary socialism which is unpleasant in the transitional stage compared to most Western countries' lifestyles?
There's a little bit of correlation vs causation that you can argue with regards to this point as well. Yes, it's almost certainly true that any revolutionary upheaval in how society is organized is going to result in a bumpy transition. But revolution is often an act of desperation, a step that people are typically only willing to take after every other option has been exhausted and the alternative of being worked into an early grave is too bleak to accept. And even then, revolution is only likely once a critical mass of people find themselves in the same wretched circumstances.
So I would make the argument that causation should actually be reversed. It's not revolutionary transition that leads to poor living conditions, it's poor living conditions that leads to revolution.
