Sounds a lot like the plot of Gattaca, and I agree that would be an awful potential effect. I do not think it's insurmountable, however, and I agree that it's unfortunately fairly close to today's current class divide.
However, I don't think such a thing could happen "overnight" as you suggest. In order for those genetic enhancements to become commonplace they will need at least several generations of trials, especially to explore how various genes interact. This long process could well lower the barrier for the less privileged to participate.
