Macron is NOT socialist (he told it himself) (Well, to be fair, he also told that he was (cf youtube link for both)). He's pure and simple right-wing. He believe that we should let the market treat workers as they please. That's what we call "Being liberal" in Europe. Its the opposite of being socialists: the government should protect the workers from the institutions who wants to exploit them.
