On Hacker News, I started to write a reply to the 11 millionth stupid article about how there's no jobs because the older generation won't retire. I started to write about how there's no finite supply of jobs, it's all about being able to create value that people want in excess of cost, and as long as any human need or desire is unmet, then there's a potentially infinite amount of work and jobs available.
Then I gave up and wrote this instead -
At the end of humanity, when the Sun finally burns out, and Earth drifts into a slow freeze in the final sunset - mankind will still not have grasped economics.
Which is probably true. (And can I attribute that to Tara Ploughman?)
