@matrixEasy, you don't pull the lever. The top row has infinity people but the least valuable person to die has a value of one. The bottom row has an infinite number of people who individually are of lower value than the first victim of the top track. Pulling the lever is dysgenic. Pulling the lever is sacrificing high value people for an infinite amount of low value people. Really it's a metaphor about non-white immigration into white countries.
