While I agree that as practiced capitalism is far from strictly meritocratic (and even in general think that any kind meritocracy is harder to achieve than many of its proponents seem to have thought about)... I don't think fuzzy conceptions of how email or other technologies necessarily refute it. Merit can be domain specific (in fact, specialized merit pretty deeply underlies most of our socioeconomic system at this point).
