Let's take France for instance,All leading project directors or mangers in leading companies in France or abroad are french (white french to be specific).I've seen project manager as young as 22years old being assigned to lead a group of professional immigrants (Moroccan, Indians, Chinese,etc).
I totally agree with bleu. Yet, i also agree with Victor Bhatt as this is the case in most ministries & government offices
