In "The Giver", where do you think the idea of "sameness" came from?

In terms, Jonas's community chose the path of "sameness" so "unfair" things wouldn't exist.

As an example, Jonas cant choose his partner in adult hood so the elders can choose the match least likely to get a divorce or act uncertain of eachother.

Another is job choices. If Jonas chose a job, he may choose the wrong one and have a terrible life. Instead, the elders choose the job he is best for.

Then there is sucsess. Some people might choose wrong choices and end up lest sucsessful than others. The "unfair" factor plays best here.
