Sylvain Catherine: Retirement pensions deserve to be at the heart of the debate on the nation's accounts. France is the only country in the world where retirees have a higher standard of living than workers, he argues.

The need for economic growth and the concern for a fair sharing of the efforts required of the country require a contribution from retired generations, he says. Catherine: Through pension contributions, those from poor families help those from wealthy families. Those who cherish meritocracy and equal opportunity should rise up against this reactionary system.
