It wouldn't really change all that much because there are still numerous jobs that sustain the society that have to be done regardless of education. The only solution to this would be if everyone's high education made it possible to create machines or robots to do these jobs for us, but until that happens people would still have to do physical work that is done regardless of education. An example of this can be house building or agriculture or factory working or anything similar. Everyone having higher education would eventually help us speed up and make the processes easier to do, but still a part would have to be done manually.

Which leaves us with B and D and what leads me to lean twards D is that the passage said that they would console him with the hope that something would occur by which I might be free, which infferes that they wish him to be free.
