Apple Inc., Google, Intel, Intuit, Pixar, Lucasfilm, eBay, and Adobe got caught explicitly colluding to fix wages (some somewhat hesitantly, e.g. Apple threatened to use its patent portfolio against Adobe if they didn't participate). Their internal communications made it completely clear that they knew what they were doing was illegal, too. They were fined a small fraction of what they saved for the wage fixing (and essentially nothing to the total impact which included people far beyond these companies due to market distortion-- when the scheme collapsed and my pay went up something like 20%, even though I didn't work for any of the involved companies). So why shouldn't anyone else do the same?
