"Metaphorically, SLABS are like Soylent Green, the subject of the dystopian movie that came out in 1973 and portrayed New York City in 2022. It's not until the end of the film that audience is told that the food that people were fighting for, Soylent Green, was actually people, processed for consumption. In 2021, SLABS are human lives, in the form of crippling debt, packaged for consumption: consumed by a range of big investors including big banks and pension funds."
