Sure, but Apple has $200B in cash, Facebook has $52B and Google has $117B. These are some of the most revenue efficient companies in the history of the world. Why risk jeopardizing that by cutting wages and potentially losing your biggest asset? I don't think they cut any pay in 2008, and Apple didn't even have a single round of layoffs. In fact I recall Apple making a bunch of strategic acquisitions at the bottom of all that.
