Men are impacted the same way. The argument in the memo is that (1) tech jobs are passion jobs for men to a greater degree than women, hence in societies where people are more able to follow their passion you'd see relatively more men in tech (2) men compete on financial success to a greater degree than women, even if this is not required for survival, so in affluent societies you'd see relatively more men in tech. This would explain why the difference is greater in societies where there is less economic pressure, even though those societies are on average more egalitarian.
