Obviously that is nonsense. Everyone at the top dopes (at least in somewhat relevant sports), Eastern Europeans just doped more ruthlessly. Whenever there is money involved, there is cheating. Makes no sense to assume that someone who isn’t doping can win gold, when the huge majority of people live in countries where doping pays off most of the time. Why should someone in Africa/Russia/China/India not dope, when they can become „rich“ by doing it and don’t really face much consequences even if they get caught? In order to outperform the most talented, doped athletes from those nations, you have to dope as well. There is nothing to suggest that people from rich nations are genetically superior and therefore don’t have to dope to beat the doped athletes from all those other nations (that represent at least 80 % of the global population/talent pool).
Anyone who disagrees has to defend one of the following two lines of reasoning and in my opinion both don’t really make sense:
a) People in rich nations are somehow special and therefore don’t have to dope to dominate the most talented, doped up athletes from the rest of the world (that makes up at least 80 % of the talent pool)
b) There is no widespread doping in poorer nations (despite the evidence from countries like Ethiopia, Kenya, Russia or China saying otherwise)
