My thinking was that time travel narratives work well and can be pretty straightforward under the idealism of liberal/capitalist ideology, but plopping a group of people into a very different society would be a much stickier concept under materialism. Not knowing any examples, I wanted to know if anyone could point me to communist cinema, literature, etc. that dealt with time travel, or had an alternative framework for exploring the differences between communities at different points in history. I also would be happy to hear peoples opinions on this topic, or the topic of being a more well rounded stem person in general.
