I don't think people understand how things work in S.A. and Argentina. More often than not people receive their government jobs in exchange for work and support for politicians. They often only have the job as long as the politicians they support are in office. When a new government arrives many the employees in government offices change. Since the people will only have their jobs for a limited time their objective is to make the most of it while they have it, i.e. shake down as many people as possible, and because they are allied in to the politicians they do this with little fear of consequences.
This is certainly not true, it is simple middle class hate. Most state workers do not change when the administration does, only some that do not work and the "upper management".
