Who wants to listen to their whiney moaning about how awful everyone and everything are?
The reality is that, despite their endless talk about the end of the system happening soon, it has not ended. People become bored, restless and resentful waiting for it to end...and still it doesn't end. Soooo, curtail the end-times talk and you open up endless positive possibilities for new topics.
That's essentially how Christianity has survived: When the end doesn't come, use distraction.
