answer:You are speaking naively and idealistically. YES, to a rational person, diversity is generally a positive – in sport, business, and so on. Although not 100% of the time. The diverse people that you hire (or add to the team) have to be contributors to the effort—putting a black or a Mexican left fielder on your team for the sake of diversity is worthless – if that person cannot hit and cannot catch a ball. So the key point in your statement has to be – if the non-white person is qualified and able to do the job he is hired for. Diversity for the sake of diversity, without quality, is actually a disservice, not a positive. Second, and more directly to your point – the main flaw in your argument is the assumption that businesses / people / organizations all want improvement. Many do, of course. But many organizations would be perfectly happy to have lily-white employees and never hire a black or a hispanic or a woman or a homosexual… these organizations don’t give a hoot about diversity or quality—all they care about is saving their safe, white, unthreatening environment. This is why you see the Republican party rail against : -fair voting laws -affirmative action at all levels -fair housing laws and so on. They’re into protecting the status quo of the 1950s, as opposed to the realities of 2014. Your mistaken assumption is that the whole world sees diversity as an advantage. It doesn’t. Many do, many don’t.
