"One quality that's a really bad indication is a CEO with a strong foreign accent. I'm not sure why. It could be that there are a bunch of subtle things entrepreneurs have to communicate and can't if you have a strong accent. Or, it could be that anyone with half a brain would realize you're going to be more successful if you speak idiomatic English, so they must just be clueless if they haven't gotten rid of their strong accent. I just know it's a strong pattern we've seen."
As I read it, unfortunately, there's nothing in this published interview that says a foreign-accented person failed to communicate or needed to repeat themselves to be understood.
It just says a "strong" foreign accent, with not clear definition of the subjective meaning of "strong".
Then, it goes astray, saying "subtle cues" could be what leads the person to business failure; presumably subtle cues that would be obvious to a native speaker. Further, not being idiomatic (i.e. not a native speaker). Thus, the conclusion is the deficiency is the foreignness, not a functional problem like elocution.
So, then I think it's pretty cutting to say people are "clueless if they haven't gotten rid of their strong accent" (emphasis mine). Since the strong accent is the foreignness, this read to me as saying Americanize which means change your identity.
I contend this is not the best way to make the point. Also, the wrong track since as we have discussed above to death the real problem is the elocution, leadership and business skills, not the foreignness per se.
However, do you think I read the interview (as published) incorrectly? I'm thinking about a cold reader, like a 21-year old woman in Tennessee who moved here with her parents when she was 12 from Sri Lanka thinking of the next big thing.
