I literally overheard some chud on a train argue that point with a friend, and used that to conclude that that's why communism will never work. If everyone gets paid the same, then what's the challenge???

He reminded me of that 20th century banker in the TNG episode "The Neutral Zone", who wakes up in the 24th century after being thawed from his cryogenic state, and then asks Picard what even the point of living is in that century if material needs no longer exist, and people's want for riches and possessions is no longer a thing. Picard skillfully schools his ass.
