I certainly agree that staff delivering public education services in France are not paid nearly what they deserve to be paid.
Regarding the comment about social segregation which comes automatically with the neighborhood you live in, I actually live in a city with perhaps the highest family income level in the Yvelines (Viroflay). Does that mean that public schools in Viroflay are better than in... Les Mureaux ? From what I understood, French schools are neither managed nor financed at the local level - as they are in the US.
