You should not confuse prescription and description. When people say things like "In order to conduct business in the US, an accent that other people can understand is important", they are describing how the world is, not how the world should be. You can say those other people should improve their communication skills, but that is just how you think the situation should be improved. The situation, in actuality, is one in which strong accents can add friction to the communications between a CEO and the people they need to talk to in SV.
