Bad news sells, good news does not.
People remember the bad news/times and can recall it more easily than the good news/times (as they tend to be taken for granted).
They stopped celebrating how 9-11 brought Americans together, but instead talk on the failures the “war on terror/Afghanistan surrender-retreat” did.
They don’t talk about what UNITES a people, but only talk of division to create strife.
This is a BIG fault with the media and the politicians.
