I had a discussion on this topic a while ago, and IMO a reasonable stance to take could be that, yeah, there might be some congenital differences among people in terms of their abilities to perform certain tasks. However, this doesn't mean that people should be treated way too differently just based on that factor. Isn't the ultimate left-wing dream "everybody doing whatever they enjoy/are good at, but treated absolutely equally"? Obviously we can't really be there yet due to a limitation on the total amount of available resources, and we do have to reward people more who hold important positions and make big impacts. However the point is if somebody is born without that much resources/luck/congenital abilities or whatnot, it's not their fault and they should still be totally respected and well treated. That could be a more sensible way to approach this instead of being absolutist. Also I still believe that luck and resources far outstrip so-called "raw talent" in the vast majority of cases/jobs, unless you are to be Usain Bolt or something. So the importance of IQ or not doesn't really change their point that much.
