It's not that I don't believe that intelligence is heritable. I do. It's more that I don't believe that it's all that important to be intelligent in order to be a good Human.
People have a natural attraction to those similar to them. In history, the over-emphasis of particular and possibly unimportant (who knows?) traits has often been the cause for wars, genocides and all sorts of other evils.
Further, I don't think that relative Human intelligence has all that much magnitude. That is - a 'really intelligent' Human is not all that different from a 'non-intelligent' one, taken in the context of other species. And, those non-intelligent ones may have particularly interesting genetics that make them important to the species, in other ways.
Humans have done pretty well as a species with lots of diversity. Why ruin a good thing? And, do you really want Humanity to be comprised of near clones?
Probably because the jobs traditionally done by the less intelligent are being shipped overseas or done by machines leaving these people in poor economic circumstances. Intelligent people would not have to be clones, smart people can be quite different from each other in terms of personality, areas of interest etc.
