The removal of the natural predators of mankind does not negate the impact of evolution, it merely forces greater emphasis on the sexual choices made by the discerning gender (in this instance usually female). Thus so long as intelligence is a breed-worthy quality (even if in an ancillary role to other factors) mankind will at the least not become "stupider". Consider, in the opening blurb, although the lower IQ couple has dozens of children, each has an extremely low probability of outcompeting any offspring produced by the high IQ couple (well assuming all intelligent people don't die of heart attacks simultaneously). Therefore, until intelligence stops being a positive breeding characteristic, it is unlikely for "de" evolution to occur. Also that term is stupid.
Second, the process of evolution takes hundreds of thousands of years, and as such a timeframe hasn't passed the only divergent quality between the "idiots" of the future and us would be entirely social/developmental. Thus with the proper schooling Joe could create the next generation to be "normal".
Third, even if sexual selection broke down mankind would still possess outliers, and it is very unlikely Joe would be the smartest man in the world.
Fourth, it is especially unlikely everyone would be fat. Assuming evolution somehow took place at that quick a pace, those with skinnier bodies are today considered more attractive in the mainstream, thus even if intelligence ceased being part of breeding patterns, human beings should have long ago selected those with higher metabolisms and outstripped the fatties already.
Fifth, in what manner is rudeness a survival advantage? If these people are socially isolated TV-children, wouldn't that provoke awe at their rare congregating? And if they congregate frequently (I.e.- the internet couch potato lifestyle has been rebuked) they should not be as naive as depicted, as again assuming magic evolution, the savvy socially would outcompete most others in the acquisition of mates.
*Note- I say the changes are evolutionary in nature as despite learning machines, Joe's re-introduction of common sense, and a positive learning environment fostered by his saving the crops, people remain stupid and apparently suffer even lower IQ scores.
Further the opening blurb is evolutionary in nature, suggesting intelligent people where "outbred".
