It’s not really a conspiracy as it doesn’t need to be centralized. Class resentment articles don’t get traction with upper class media gatekeepers but white guilt does. So the market produces what the gatekeepers want.
I do enjoy CNN anchors lecturing and belittling middle America from Martha's Vineyard. It's some sick fetish of mine. Equipped with the latest air pod pros and Zoom they don't have to leave their beach front properties.
