Only Westerners (mostly Americans) are convinced that the end of the world is coming. Ask the Chinese what they think of their prospects, and the answer is "never better".
Here in America, we're just indulging in endless guilt, self-recrimination, and existential angst. The rest of the world is out there progressing. We're squandering the saved capital of generations because we no longer understand where wealth comes from, while China, India, Iran, Vietnam, the UAE, and other nations are producing, saving, and investing - they're going to be the First World of the 22nd century. When there's a problem, like disease, or water or food shortages, free & productive people don't whine about it - they make a profit by solving it.
