> The president still can lose their majority in parliament, they still can have an hostile prime minister, and they still don’t control the judges Technically, yes. But the justice system is famously a ritual authority abiding by the execute power (see Michel Foucault), while the legislative body is ignored by the executive branch whenever they feel like it without any form of consequence (that became a national debate under Sarkozy, and is still a scandal with the health pass). France is a republic on paper, but in practice is an electoral monarchy with absolute powers for the president. Also worth noting, all these people from the legislative/executive/judiciary are from the same caste/class and are very conscious of their material interests. They may disagree on a few policy details, but when it's about fucking the people to protect big corps and State corruption, they all stand as one.
