Ever since the History channel only showed bullshit and create a more superstitious audience I really do believe promoting superstitions and expanding folk cults around crypthid, ghost, psychic, and promoting worldviews of supernatural over the natural prevents people from understanding the world and isolating them from the levers of power. Believing in impossibly strong governments and impossible to understand enemies leaves the working class dis-empowered and afraid. This effectively creates mass psychosis among the populous. Spree shooters are reacting to their loss of privilege and how they are misinformed that an individual with a gun killing people can somehow liberate the world from some impossible enemy. Actual gun violence only reinforces the horror and encourages people to disengage from knowing what is going on.
I suspect the US government is funding or subsidizing this psyop, but it could very well be the institutions of capitalism finding a way to scare people as a marketing ploy. But why would the government not try to make a profitable market to consolidate their power? It's self funding!
