But ... "fair" pay does not mean the same thing as "whatever is financially best for the company to pay its employees". Take the other end of that bargain: is it fair for Mozilla to pay their janitors a reproduction level wage? Most of us (except the hard core right-wing libertarians) say no, that's why we have a minimum wage (which many of us also think is too low).
The elision of the distinction between "fair" and "whatever the market rewards you for doing" isn't an argument, it's just crass market-worship.
Edit: this post is pretty clearly argued, and downvoting without even a comment is exactly the kind of ideological nonsense that this site simultaneously prides itself on not doing (contra Reddit), and yet hilariously symbolizes.
