True, I'd agree that my wellbeing today (as a member of a rich western country) is far more preferable to someone who lacks modern innovations. However, these innovations continue and will continue to help the rich far more than the poor. For example, medical treatments for life threatening conditions are still incredibly expensive. Even insulin, something so cheap to manufacture, is being gouged to eyewatering prices. The danger is that the disparity becomes so large that the rich become the only people who can afford these innovations, thus leading the innovations becoming only avalible to the rich and not the poor. Structural violence ensues and pretty bad things happen.
