Ah yes, the efficient markets theory - never before debunked ;-) Jokes aside, the truth is that with the original definition, there are so many barriers to markets being efficient and behaving in that idealized way that in reality I think it's a unicorn that can't exist, or at least rare enough to take with a huge grain of salt. It's a simplified model of how things might work, and perhaps if you squint a little it does seem to work that way, but not when you look closer. People behave irrationally all the time, there are all sorts of factors and incentives, social, political, and game-theoretic, that prevent actors from operating in certain desirable ways. I think it's hilarious that Chinatown may have out-capitalisted the capitalists, and cut out many middlemen to deliver better product for cheaper. Sad that they probably won't get much recognition for it, perhaps only some lobbying to block it.
