In recent years, a powerful narrative has swept across corporations, governments, and educational institutions alike: diversity is not just a goal—it is a moral imperative. The prevailing assumption is that by gathering a mix of races, genders, backgrounds, and identities, society will automatically produce better outcomes. From boardrooms to classrooms, the mantra of diversity, equity, and inclusion (DEI) has become almost sacred, treated as both a shield against criticism and a litmus test of moral virtue. Yet, despite the good intentions, we have gotten it wrong. We have mistaken diversity for strength and fractured unity for moral progress. In the process, we have overlooked a foundational truth: the cohesion of a people, a team, or a nation—rooted in shared values, vision, and purpose—is what truly drives success.
