the gender wage gap argument IS a bad one: for the same reason that this memo is bad. it's much to vague, and assumes that unknown variables must be connected to a predetermined conclusion.
let me show you
1: basic pay gap economics.
since the overall pay of women and men in 2016 differed at about a ratio of 7:10, then the difference must be from sexism.
the truth is, pay bias happens intermittently throughout industries, but it's hard to precisely measure. the reason is that any pay bias that IS proven, is almost immediately taken to court or revised. the pay biases that are NOT proven, by very nature, are not being measured.
2: the memo
because there is a difference in the hiring rates of men and women in google, despite diversity programs, the reason for the differences in hiring rates must be due to some genetic factor.
the truth? while there might be some slim genetic factor contributing to this, IQ is not a valid measurement, and he provided no other evidence. unfounded claims are not good science. furthermore, there is a great lack of consideration of pre-job socialization and education of women compared to men. attacking google for being far to the left (although more observably true than not) is NOT evidence for bad discrimination.
frankly, the memo was way too over generalized. perhaps google DOES have some hiring practices for "diversity" that are bad, but since the memo does not actually dwell into specific google policies, or specific items in their legal code, there is no sustainable claim being made by the memo.
the ENTIRETY of the memo would barely serve as a good abstract for a larger paper, much less stand on it's own right.
