The guy pointed out what 36 cubic feet actually is. The cubic root of 36 is 3.3 feet, or about a meter. That's either a coffin or a cage, depending on how you divide out the space. That's not how "most people" lived in the past, nor is that the tiny cell the bugman is in the photo.
Maybe his idea of the future is like Maddox's is, where all the "smart people" live out their lives in life sustaining coffins hooked into VR while everyone else has to work under robot overlords to sustain the systems.
