Not every monopoly is created equal and if you can not acknowledge that you are not arguing in good faith.
Edit: also I am looking into De Beers a bit more and it seems the EU has made steps to improve competition in the past.
Also if you want to argue that LVMH is a monopoly and that it has a bad impact, go ahead. I just think that since this is HN it is natural that most people do not feel the impact and do not really care. I do not know exactly how monopolistic they are and what the bad impact of that is but feel free to enlighten me.
