Actually, I think that once intelligence and beauty can be "fixed", one could argue that the line between being disabled intelligence-wise (or aesthetically-wise) or not starts to shift. All those millions of children who, in your scenario, don't have to live with a disability will also be at a steep disadvantage compared to the extra smart and beautiful rich kids. If this would continue for some generations, you'll get a genetic upper and lower class. It could even mean that we create a new "super species" that's becoming less and less compatible with humans . (Yes, I read way too much science fiction, but I think it explores some interesting scenarios we should seriously consider while debating the issue. For a very popular reference: In the Star Trek universe the Eugenic Wars explore problems of genetic enhancements; The character Doctor Bashir in DS9, for example, is an (illegally) enhanced human [http://en.memory-alpha.org/wiki/Julian_Bashir] http://en.memory-alpha.org/wiki/Julian_Bashir])
