This “pure meritocracy” argument simply boils down to the fact that it’s not possible to build a system that perfectly measures how prospective candidates will perform in the future. Really, all businesses and institutions should be free to innovate their own methodologies for doing that, and live with whatever consequences they produce, with the governments role being to regulate the limits of permissible discrimination. Race has been a class legally protected from discrimination for quite some time now, and it’s honestly pretty sad that it’s taken this long to get a ruling on this open and unapologetic racial discrimination.
