To argue that Bernard Arnault is clueless in economics is beyond absurd. He did not inherit this wealth. He did start with a family operating business, yes, but nowhere near his life result (and "the job" not even complete yet). He grew his group entirely in one generation - and so, yeah he has a pretty good grasp of economics.
Biased, sure - like most of the french population where being opinionated is normal. Clueless, no.
I don't know anything about him personally, but if he's that rich then I'm certain he has a highly paid team of extremely expert and well-informed people that are giving him his information. I take what he has to say with a grain of salt since he has such a massive self-interest in this, but still worthy of examining his arguments
I don't know why what Bernard Arnault says is on HN, he has no competencies in economy.
No dumb rich-hate here, simply that Bernard Arnault is definitely not best person to talk about the subject.
