"Life on a lifeboat isn't much of a life. It is like an end game in chess, a game with few pieces. The elements couldn't be more simple, nor the stakes higher."
The idea that we will make a society where literally everybody is graded, the good at the top, bad at the bottom, exactly done as it should be, is impossible. There are simply too many random factors: accidents, accidents of birth, accidents of things dropping on people's heads, illnesses, etc. We will never get to grade them, never get to grade people as they should.
The system produces needs faster than it can satisfy them, and thus it perpetuates itself.
