  The use of reprogenetic technologies to select or edit embryos can contribute to social injustices in various ways. For instance, given the significant costs of these technologies, its use is likely to increase inequalities between people who have the finances to afford them, and those who do not. The wealthy already have advantages; if we allow them to select or edit their offspring for improvements  – so that they are smarter, faster, stronger, with less need to sleep, etc. – those children will be ever more competitive, and liable to increase the divide between rich and poor. (Lee Silver explores this dystopian possibility with the GenRich and the Naturals in his Remaking Eden, 1997, though he still supports the use of these technologies.)
