To me the takeaway (politically) should be that since all humans are created equal (morally) but are unequal (mentally/physically) we should re-evaluate how we reward work in our society.  Physical and emotional work is often very undervalued in our society imo. How much value should we place on having clean streets, or having our elderly cared for compared to designing clean energy solutions?  I would argue that these things are equally important. Since the person who designs clean/new energy solutions is more rare I understand the desire to pay them more. But I don’t understand why the gap should be so large. I want the person who is caring for my parents or taking the garbage to the landfill to make a good wage so that they can have healthcare and support a family and have a few fun extras. Every job is important, especially the “simple” jobs like cleaning/transportation/logistics/care.  Just because you have a lower IQ doesn’t mean you should be so poor that your life is a constant struggle.
