A meritorious person is elected by those qualified to judge merit for that specific position of power. The most informed people, who are making the key decisions, will have no interest in media reports. Experts in a particular field are far better informed than the media could ever hope to be. Can you imagine Bill O’Reilly trying to tell pharmacists what drugs to prescribe? He would be laughed out of the studio.
In democracy, media propaganda is very dangerous; it makes foolish people hold strong opinions on issues that they are clueless about. But when the electorate is made up of highly informed specialists, there is no threat that propaganda will determine policy. In Meritocracy, the media brainwashing machine is completely disarmed by the collective influence of qualified experts.
