Do we really want justice?

In The Republic, Socrates goes very far in depth into how to form a just society. The thing is we really can't just skip to forming the just society that Socrates proposes because to start the society he proposes, he states that you really have to start from scratch. The question we have to ask ourselves is we want to start over and erase everything the human race has done in order to form a just society. I just want to examine some of the statements Socrates makes in regards to making the just society. Socrates says we have to make entirely different stories in regards to heroes and people in order to somewhat trick the guardians to become the ultimate protectors. First of all I want to state how strange and possibly unjust this is because you are tricking people into believing what you need them to be. Another thing that Socrates states must happen is that everyone must be specialized in something. In our society today, we know that people want to be good at lots of things and not just one. Another thing that I want to point out is that people would be too opposed to the idea of starting over fresh since the human race worked so long to reach everything we have reached so far. There is no way that anyone would just want to start over to make our society be just.
