Plato wrote in his "The Republic"
Each member of a society ought to do what they are best at and be alleviated from responsibility of those things they are not good at, which can be done by others.
I often wonder what kind of world this philosphy would create.
How would it be, if Johnny started school in the fifth grade, past the grade of his olderer sister in the second?
I think right now, capitolism and free enterprise tries to allow us to find our own levels in society. And I wonder how well that is working.
To me, the levels we find still seem to be determined by wealth and locations that present opportunity; and not merit.
Brilliant minds are rarely discovered in Podunk and feeble minds often have highly financed degrees.
