The reason they get paid more than you is because their industry generates more revenue than your and/or its shared more equally.
Wat? When was I complaining about people making more money than me?
Who’s to say you don’t do more work because you are inefficient?
Again. Wat?
We're talking about statistical averages across the whole economy here. Statistically, the women protesting against the pay gap are protesting so that they get paid "equally" for less work.
Unless you want to suggest that women are generally more efficient in their labor than men are, you're talking crazy here.
And if you do want to suggest that, you're still talking crazy.
