Why would we want a society of geniuses though? Most people are truck drivers, retail, Human Resource people, nurses etc. You think they whine now about things being unfair, just wait until the people whining are whining because they really do have the ability to do more rather than just being resentful.
The idea of a society of geniuses is something I've been led to and thought over many times. I'm not sure what such a thing would look like. I imagine there would be a potential decrease in violent crimes that are high risk low reward (armed robbery for example), but there would likely be an increase in other types of crimes. It's hard to predict with any real certainty though, IQ is correlated to certain behaviors, but it would likely manifest in different and unfamiliar forms if everyone in the population were to exceed a certain threshold. Also it is difficult to say if new ideologies and such would arise in such a population.
There is indeed that fact that every society thus far relies largely on the reality of some individuals sacrifice more than they gain, and it is certainly true that this process works smoother when the exploited members of society are unaware of the fact that they are getting a raw deal. That being said, even today many still contribute to maintaining the status quo even though they are conscious of the fact that they are getting screwed over (although maybe they dont always realize the fullest extent of the exploitation), so it could work. Some people may still choose to engage in those jobs out of a sense of honor, ego, religious belief, or any other spook/cope. Intelligent people are still people, and are still susceptible to many of the same flaws.
There is also the possibility that automation or technological advances would reduce or entirely remove the need for much of the manual labor workforce.
It is difficult to say what a high IQ society would look like, but it would definitely be something very different than the current system. Maybe in such a society, each individual would be far more mercenary and self interested, or more accurately, far more capable of attaining their goals through adoption of effective strategies, and thus harder to exploit. Most likely there would be a requirement for far more constraints placed to keep the game unfair and to keep the lower status groups down. Or things would need to be designed such that theres incentive to engage in behaviors that are mutually beneficial (although this eventually runs into a wall due to mutually exclusive, conflicting interests). Or hey, maybe everyone works together and creates a utopia (lol). Its a fun thing to think about.
A fun last point is that IQ is not an absolute measure but a relative one, so technically if you raised everyone's IQ to what is currently 130, then an IQ of 130 would just be 100 in this new population.
