There is absolutely nothing wrong with people, individually or collectively through their companies or unions, contributing to political parties, if it is within reason and it is done in a transparent manner so everybody knows where the money has comes from.
Le fait que des gens, individuellement ou collectivement, contribuent aux partis politiques n'a absolument rien de répréhensible si le montant des contributions est raisonnable et s'il y a transparence afin que tout le monde sache d'où vient l'argent.
