Imagine a world where…

Please stick around to read the wall of text. Imagine a world where every person had a number value floating above them, attached to their persona. It doesn't have to be a physical object, just a value that everybody can see. This value is calculated based on a combination of your skills, talents and qualities. Everything would be accounted for, and the calculation is somehow perfect. Call this a 'rating', if you will. The higher the number, the 'better' the general quality of the person, everything taken into account. For kids still maturing, this value would be adjusted to be somewhat based on potential as well. Now, for the questions. How high do you think your number would be? How do you imagine this would affect the way people treat each other? How do you think it would change how people choose their partners? Would this be a blessing or a horrible, horrible thing? I'd like your opinions and any sort of inputs from you guys. This is just something I thought about one evening.
