So, how do you decide who gets the rewards? Assuming not everyone can have every job/house/life. Do you tell the people who get the rewards that they were given a chance at random (compared to their neighbor who was not) or do you let them believe they earned it? For the record, I agree that merit is a bad system. Im curious to explore the ramifications of doing away with the system and how it would be different, if at all, from the current system. For example, in a post-scarcity society, everyone has what they need, but some houses still have nicer views than others.
