So people are slaves to the State, they have to do there turn at the distasteful jobs.
What happens when on your day to clean the floors, you do a poor job of cleaning the floors? Or just sit there and text you friends?
Would the schools at this time also be ran the same way , so that they don't give out grades and everybody gets the same grade?[/QUOTE]
You're projecting your own experiences with your society onto a completely different social model. Niether anarchism nor the kibbutzim are statists societies. The idea of rotating task is to de-stratify society not the reverse. Also, the same people doing menial tasks would also be rotated into administrative tasks at their trade union and local committee as their turn comes up. So everyone in society takes equal part in the management of society not a priviledged ruling class of bureaucrats, capitalists and specialists, which is what we now have under our existing system. The prevailing myth in present society that some, not all, buy into is that we all have an equal chance and that merit ultimately determines your station in life when in reality the overwhelming majority of people (rich or poor) are born into their positions and rarely transcend them. Are you one of those rare exceptions?
Granted some positions can't be rotated; engineers, doctors (Scotty & McCoy), etc. Other red shirts excepted, of course.
"The only exemptions from this rotation are the ill, the aged, and teachers. An inconvenient job such as that of night watchman is also filled by a rotation system, the period of service being for two weeks." Kibbutz: Venture in Utopia by Melford Spiro
Re: school grades, again you're projecting your value system, based on your cultural experiences, onto others. Different societies/cultures/economic systems will use different methods. Does that make your's or their's superior?
