The song talks about slavery where it still exists, as well as human exploitation and cruelty to women (sexism etc.). Although Taylor Swift enjoyed her golden year in the musical industry in 2010, she has been changing musical styles ever since her fourth album, Red, was released. Take this song, for example. It contains lyrics relating to cruelty, slavery, evil, dread, gloom, and exploitation. Plus, since Taylor Swift seemingly took a peek into how people can be buried alive, we can prove that she was buried alive once in the pre-chorus.
Therefore, this song is, in my opinion, a mess compared to her past songs, the majority of which didn't contain lyrics related to cruelty, possibly due to the lyrics relating to cruelty and slavery, as you can hear throughout the entire song.
