Really? When I started working in the ‘70s women were routinely underpaid and overperforming for the level they were promoted to. Never have seen women routinely promoted because they were women—and certainly not able to do only half the job of a man who preceded them.
They largely are simply not interested in your typical STEM job, But they are often good at marketing, account management, PR and HR jobs, for example, at tech companies.
I expect there are a lower percentage of women than men who would be very good at coding, engineering, etc. But if we weren’t obsessed with social engineering that really wouldn’t be an issue.
What type of jobs did you see them in pairs replacing the work that a single man had done previously?
Mostly accounting functions.
It actually works for everyone because they tend to be older and hire a buddy (usually of similar age), so younger workers have a measure of security in fresher skills/more recent education - and we ALL get to work the bare minimum hours they work (these aren’t the “tip of the spear”; they’re working half a man’s job). They set horrible examples, so it is easy to shine in that environment.
