If we wanted to have a field of science dedicated to the use of targeting a magical gene and perhaps selling it or altering it, in case someone doesn't want their child to have it. We could probably do something with upper and middle class if that was the case, as I assume if the gene itself became a commodity, then it could be something the wealthy either abhor or want a monopoly on. Either way, I can see class system dynamics working in some way with magic v non-magic users, then of course there's the idea of putting them in the military and all that, though I'd have an idea that only certain parts of the world can have native of certain magical affiliations. What do you think?
I like the idea of a magical gene adapting to the enviroment to suit survival on it properly, in a way that different regions of the world have different kinds of magic; in the past there could have been slave markets in order to use the people with said genes and to transmit them. That's pretty dark, though.
The class system is fine, it'd seem logical that the people with the power to transform their enviroment without relying on machines or workers would have had an advantage in an early stage of civilization, although nowdays it could be rejected. It does depend on the person. And the military... that's an entirely different issue, there's the fact that a nation that conscripts its magicians will have more power, yet in a modern society the individual would have the choice to enroll; which leaves us with the problem as to why people who hold economic power would enroll willingly. Perhaps because of honor and tradition. There's also the fact that in a modern age, no matter how powerful a magician may be, he can't hold an entire army at bay like they could before, when they defended fortresses from the top of towers. Most of the army would still be composed by regular humans.
