It's more than that though. Memory is a series of boom-and-bust cycles. Also, it costs around $15 billion and takes 2-3 years to build a fab. So if you were to start now, you'd have a pretty good chance of hitting the next bust right after spending $15 billion. It's not necessarily some sinister conspiracy, it's because execs are reluctant to be the ones to take the blame for setting fire to $15 billion. Looks kinda bad on your CV.
