That varies depending on what data you look at. The link I provided above accounted for all of 4%. The other thing to remember is that there could be other factors that we just haven't thought of yet--that remaining 4-7% could very well make perfect sense, as has the other 17%. The point is that it's a very small deviation--small enough that any efforts to "correct" it, should it even need correcting, would almost surely hurt everyone involved more than help them. As I stated above (maybe in a different message), the market does not reward discrimination. That doesn't mean that it won't exist, only that a firm places itself at a competitive disadvantage if it discriminates[1].
[1] Actually that's really only true when society detests the discrimination in question. It could certainly be plausible that if a society detests brown-eyed people working in factories (for whatever silly reason), any company who attempts to hire a brown-eyed person to a factory job would be boycotted to the point where hiring that person would be a net loss, even though otherwise his hiring practices may be at a competitive advantage over the competition. Suffice it to say, I don't think society detests women being paid on par with men, given it is an apples to apples comparison, so I don't think this analysis applies.
Ultimately I think he communicated the same thing that you did, but in fewer words. He didn't say "women who act like men are paid more," just that when the behaviors are the same, which would include career choice, child rearing decisions, etc., the pay is the same. There is *nothing* sexist about that statement.

I rarely read signatures, but I did read yours.
OK this will be my last response. First of all, aren't you conflating financials with economics? While on a balance sheet, you may be able to say that building out infrastructure is simply a shifting of assets, but that is simply not true economically. Economically, we cannot say that built infrastructure is worth the same as the money used to build it, as value is entirely subjective. Whether or not the infrastructure increases or decreases in value (as represented in units of dollars, although of course value and money are not the same thing) is determined by whether society (internet service consumers in this instance) prefer the resource in its former or latter state. If Comcast invested $500 million in a vast infrastructure that no one wants and thus has little or no value, then that is certainly not a $500 million asset (it may be when looking at a balance sheet, but not economically).
As for AT&T, you're completely changing the subject. Not only that, but you're just throwing random anecdotes around without anything to substantiate, such as: "They were a monopoly and they gouged us." Interestingly, then you concede the argument: that innovation overthrew the monopoly. Okay, yeah I'm being facetious. But you do get my point, right? Competition need not come strictly from another company trying to offer a very similar service or product.
I concede it may not be possible for Comcast to grow their cable business. I thought of the same constraints you mentioned before I submitted, but wasn't about to make your argument for you.
The last thing I take issue with is your idea of what a normal firm does vs what a monopoly[1] does. Both firms seek to optimize their prices and capacity as to obtain the greatest possible profit. A monopoly is not the only type of firm who may want to reduce output to increase prices and ultimately gain a greater return.
[1] For the record, I reject your definition of monopoly. It is arbitrary to assume that the optimum number of firms in a given market must be between x and y.
Always draw your curves, then plot your reading.
