I like the idea of an alternative "artificial" selection and I agree with most of it. I did imagine something like that some years ago, so it's nice reading it here. I was thinking of beauty standards being the major force behind the selection, but I like your thought process too.
As for the main topic, I believe (or hope) that a redefinition of our society on a global scale will eventually be needed. In my opinion, our best option to survive as a species is to overcome the concept of national governments and create one big (and actually useful) UN government. Even then, our energy problem could eventually force us to change our lifestyles entirely. We'll probably live in a more organized way like ants do, like making use of public transportation exclusively, which means adapting our entire daily routine on what other people do.
As an example, all students of a certain university could be required to live in a single building or city block, and have roughly the same schedule. Same for the workers of a factory and so on. Basically, we might have to adapt our life based on the collectivity's needs. That might also imply not being able to choose the career we'd like, because our city could need more firefighters than doctors.
