Ah, but OP said "we don't need proof on that" so none of that is relevant. He feels like every American industry has collapsed and failed over time.
Stephen Colbert invented a word for this all the way back in 2005. I suspect the condition has become even more prevalent since then as social media has grown, allowing everyone to envelop themselves in a bubble of like-minded individuals who echo shared beliefs back and forth so that it seems like "everyone" agrees with them.
I don't know that it's become more prevalent, though, since I haven't researched the topic from external sources. So don't echo this sentiment elsewhere unless you want a visit from the Irony Fairy.
