In politics, Macron, joined the PS at the age of 24, does not waste his time remaking the world with thirty-year-olds. It skips a generation. And very quickly puts himself at the service of François Hollande. He met him for the first time in 2006 over a drink with his lifelong friend, Jean-Pierre Jouyet. Immediately, the current passes. They see each other occasionally. Then very regularly from 2010. It cannot be said that the Rothschild banker came to the aid of Hollande's victory. For him, it was the deputy for Tulle or nothing. “I was convinced that he was the man for the job after five years of Sarkozyism. He has France in his flesh.” Both are made of the same wood. A close friend of Macron: “Like Hollande, Emmanuel is at the same time sympathetic, not very divisive and of great ideological plasticity.” From the left, he is. But a rather liberal left, straddling the restoration of public finances and the free play of the market.
