I totally agree, mainstream media is a dog and pony show in most regards. The trick is to educate yourself on political economy, propaganda, and ideologies, so that you can extract underlying meanings behind much of media. For example, by coming to understand the concept of manufactured consent, and the role the private media in the U.S. plays in reinforcing state ideology, you can more clearly see the role that they played in creating support for actions the government intends to take, eg. The rapid spread and use of misinformation and failure to effectively fact check State Dept claims during the lead up to the war on terror. The media was effectively complicit in ensuring that any deviation from the party line they were to hold was sidelined, and even when presented, made into a straw man for ridicule. We can also look to former CIA and FBI officials who publicly acknowledge their use of human assets, either knowingly or unknowingly, to spread false information and create a desired public response.
I could say more, but I just got a video call, so I will have to stop here.
