The historian/philosopher William Durant pointed out (in my opinion, correctly) that people's contentment and fear of the end of the world are two compensatory buckets in a well; i.e., if you're happy or content, you don't think much about The End of Everything.
Contrariwise, if you're not happy, you tend to wonder if the troubles in the world aren't signs and portents. It's been like this since the eschatological texts of Daniel, Ezekiel and Revelation were written, and it'll be like this for many centuries to come.
But that doesn't stop people from going on and on about it as if it's about to happen, and that frankly annoys me. It's bad enough that these idiots are trying to ram their claptrap down my throat, but they indulge in the worst kind of Magic Thinking - the idea that all of the nastiness going on doesn't need any practical solution, because Someone will come and make Everything Better.
Next time some loon tries to lay that on you, ask for all of his or her money - since they won't need it in Heaven.
