I didn't have the patience to finish The Fourth Turning [1], but it's arguing that the US has been working on 80 year major cycles for a long time. I like "end of a cycle" better than "end of the world." :) I'd be interested to know if there are related studies outside the US.
Something I didn't learn about until recently [2] was Glocalization. Wikipedia [3] says it's been around since the 80s. Perhaps now's a good time to bring it out again.
