Looking at human behavior through the lens of memes seem to be a very way of understanding people and society and getting some interesting insight.
Our brains have evolved in a way that allows for memes to spread, survive and evolve themselves. I think that's one of the things that has made us the success story that we are as a specie. But as a great deal of the rest of our evolutionary adaptations connected to the way our brains work, our ability to spread and be affected by memes has kicked into high gear in the modern work in a way that is not always beneficial.
But you are right, if you want to understand human behavior, memes are a very powerful concept. Now that you've pointed it out, it suddenly seems quite clear that pretty much all market bubbles can be explained in that way quite reliably.
Congrats, you just infected me with a meme... :P
