The mainstream media is the house organ of the U.S. government. From Caitlin Johnstone at caitlinjohnstone.com:
The US State Department’s spokesperson Ned Price is being replaced by a man named Matthew Miller. Like Price, Miller has had extensive prior involvement in both the US government and the mass media; Price is a former CIA officer and Obama administration National Security Council staffer who for years worked as an NBC News analyst, while Miller has previously had roles in both the Obama and Biden administrations and spent years as an analyst for MSNBC.
Like every high-level government spokesperson, Miller’s job will be to spin the nefarious things the US empire does in a positive light and deflect inconvenient questions with weasel-worded non-answers. Which also happens to be essentially the same job as the propagandists in the mainstream media.
In journalism school you are taught that there’s supposed to be a sharp line between government and the press; journalists are meant to hold the government to account, and there’s an obvious conflict of interest there if they’re also friends with government officials or are looking to the government as a potential future employer. But at the highest levels of the world’s most powerful government and the world’s most influential media platforms the line between media and state is effectively nonexistent; people flow seamlessly between roles in the media and roles in the government depending on who’s in office.
