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 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.
