Truth. Any extra resources in the public school system - which let's face it, there are no "extra" resources in our current public school system - are devoted to bringing those on the opposite end of the spectrum up to grade level. There are very few programs and opportunities to advance a gifted child within the system.
Public schooling in the US is not for gifted children. Your only viable options are home or private schooling. The child's opportunities for learning and enrichment are only going to be as good as the resources and involvement the parent can provide.
I think I agree with your statements but not you conclusions.
Schools with lower enrollment have less classes. Which means less room for variation because teachers need to teach a whole class. Within a class, it will usually be brought down to the lowest level (of those who want to learn), exactly as you say. But, with lots of different classes you have room to have advanced classes where the ahead-of-the-curve students may be placed. The "lowest" among them will be higher, raising the bar.
Private schooling (which costs more so parents are often more involved but pays teachers less), doesn't have as many classes so it doesn't have the scope to separate out as much. Now, they do have a reputation for being tough and good schools, and I thing as a generalization they will take moderately below to moderately above students (say, one standard deviation in either direction) and raise them above the average level of a public school level, but I don't think they are best suited to the extreme outliers.
Personalized attention is what the true ends of the spectrum need. I can see how, with the right "teacher", home schooling can fill that niche. Though with how far off the curve this child seems to be, I would assume adding in subject matter experts as tutors to keep him challenged (and therefore engaged).
