I think you're misunderstanding my point. My point was not that there's not human suffering in the diamond industry, nor that it isn't bad. My point is that you, a person that cannot afford expensive natural diamonds (speaking statistically here, I don't know you personally), probably should not cast moral judgments on others that can and do purchase expensive natural diamonds. This is due to the fact that you, a person that can afford a cell phone, chooses to purchase a cell phone, despite that industry experiencing similar levels of human suffering. Therefore, I am forced to believe that in the counterfactual world where you can afford expensive diamonds, you would buy them.
