It's not a jab; it's a simple statement of fact. That's what I've seen in my (entirely US-based) career so far. And I'm not personally the kind of person who's interested in euphemism and beating around the bush purely for the sake of euphemism and beating around the bush.
Note that what I was suggesting was not anything like, "Ignore white dudes and only talk to everyone else." I was saying, "A less informal system may be less impenetrable to people from other social backgrounds." Presumably, in such a situation, white men would still tend to be a plurality of voices, because that's just how the workforce demographics work out in the US. But, even given that, why wouldn't you want to make sure you're also doing a good job of giving full voice to folks who come from the other 2/3 of the population? Even if we frame it in purely mercenary terms, wantonly underutilizing employees' talents is probably bad for business. And relying on invisible, socialization-based mechanisms tends to have a poor track record in that department.
