I never really got the argument against augments (in universe as well as from the writers).
All the humanoids in Star Trek are the result of genetic augmentation anyway.
The whole "eugenic wars" thing always felt like a cop-out because the writers were to afraid to tackle a controversial topic during the actual show and pushed it into the past in a "we already had this discussion" kind of way.
Of course the super rich would immediately meddle with their offspring if they could.
But his would not produce any kind of superhuman.
We barely understand how the mind works, attempting to make someone more intelligent with genetic manipulation is like poking a haystack and hoping that a needle finds its way to the top.
Technology that advanced is like 100 years into the future at the earliest.
The best we can do is to change your hair color and the way your sweat smells, that kinda thing.
People are racist even without the help of genetic manipulation so it would change absolutely nothing of consequence.
