It feels like whoever came up with this plot was a timid and tormented teenager with a point to make about the revenge of the working class over the over-influent. This movie is the answer to "what if you made a snuff movie but with a good director and good actors".
I really wanted it to have an ending that would tie everything together and explain at least some of the absurdities and gore of the movie, but no. The point of the story is that there is no point to the story.
Go watch cat videos on YouTube instead. Or non-timelapse videos of an apple tree growing. It'll still be a better use of your time.
