There is more to fitness than the state of having been naturally selected and ability to breed in that context. Ability to be selected for new environments and to breed in them is also fitness. A species can breed such that it is the most fit for its current environment while losing ability to adapt to a new environment.



What I'm referring to is more along the lines of fixation and along the lines of how Frequency-dependent selection is the hypothesis that as alleles become more common, they become more vulnerable. The resultant product of a species that breeds randomly is different ability to adapt to new environments. It's like comparing how a diverse collection of corn may have in it subsets that are more able to resist a new pathogen, yet if you bred all corn together long enough, that same pathogen would more likely wipe out more/all corn.



Are they available to use for every subsequent generation? Do they appear at an unchanged rate?




I get this. It's because in the real world there is environment differentiation. The hypothetical was in response to an idea that didn't include environment differentiation.


BTW I am not, have never been, and do not consume material by race elitists or xenophobes. The idea I expressed I got from the best mathematician I know of. Sadly I can't find the reference again because everything gets buried on Twitter.

Well I guess it's fitting that the closest analogue study you could find was done on corn. At least you're placing your subgroup of idealogues on the right branch of the tree of life.
This also relates back nicely to the discussion we had about how automation could replace creative jobs in the near future, because those insults write themselves.

Regarding fixation: Even in the most ideal abstract models, alleles will reach an equilibrium rather than get fixated. It takes some serious population bottlenecks for fixation to happen in the wild. If you feel like torturing WolframAlpha, you can plug human population numbers into those equations.

A good question to try to answer for yourself in this context would be why recessive alleles don't just disappear, and why recessive alleles that objectively suck for evolutionary fitness don't disappear either.
