I think it's a leading question to use the word 'contribution' as this denotes surely something positive.
Macron, like other French presidents is trying to remove the traditional employment protections given to civil servants. This is part of a decades old trend in the West and now internationally to change the balance between public and private sectors through new public management policies. However, unions and civil servants are continuing to resist this move. Will Macron succeed where others have failed? Luc Rouban from Cevipof has writtne and researched these developments.
The election of Macron has transformed the political landscape of France. There were needed and unpopular reforms which President Sarkozy and President Holland failed to achieve because of the constraints from the traditional political party systems (you were either from the left or from the right). President Macron doesn't have any of those constraints, and the fact that he has majority in the parliament allow him to achieve lots of unpopular reforms. He will for instance allow more PPPs. He will progressively reduce the wages charges of civil servants by contracting out more public services to the private sector. He will promote more start-ups. He is being called the president of the rich because of his tax reforms, but I think those were needed reforms which will attract more investors.
