Annalee Newitz wrote a really interesting essay on how economic anxieties are creeping into fantasy and science fiction stories. From The Rise of Dismal Science Fiction:

We’re used to science fiction providing us with commentary on technology, and vocabulary to discuss its more worrisome consequences. But underlying our fears of robots stealing our jobs or corporations turning us into consumer droids are more basic anxieties about money—and science fiction is increasingly reflecting that. For audiences grappling with the fear of poverty, or simply bewildered by postmodern economics, stories like Game of Thrones, Black Panther, and Malka Older’s critically acclaimed novel Infomocracy function like Aesop’s Fables for the 21st century.

My current favorite sci-fi series, The Expanse, is another great example of this. Yes, it’s a story about space and scary things, but it’s mostly a story about inequality and economic oppression.
