The echo chamber is also magnified because instead of just celebrities appearing to live charmed lives, these guys see their neighbors, peers, friends, and co-workers seemingly living it too, in photos and videos posted to their social media accounts. They try to escape it but it's all around them. Even when they go on porn sites they see the same amateur Chads and Stacys fucking and sucking in porn videos and live on webcams, having fun, earning money, and winning at life. They buy into the facade that everyone with a social media account creates to increase their brand. This compounds the feelings of isolation, defeat, and failure of the incels. Meanwhile, the incels are saddled with debt, have palms hairier than their asses, are socially awkward, and have no genuine future prospects beyond the daily brown-nosing grind. This is what leads them to do what they feel is their only option - to pick up arms and go to war with the Chads and Stacys whose existence is their humiliation.
