Okay, so spoiler alert, I'm grinding an axe right now.
It's completely ridiculous to imply that analysts are not normalizing for hours worked. That's one of the most basic things they do, and you really should provide proof in the form of a study that both published its methodology and has been done in the last 5 years that didn't account for this, setting aside that one clickbait publicity stunt from Glassdoor. People keep citing other studies that "don't do this" and it's not true, or point to the national average and say that extends to knowledge work and that's absurd.
"The pay gap" is not simply lockstep salary progression. It was just the most obviously unfair and lowest-hanging fruit. That's only the start of it. The fact that women are often passed over for promotion because industries frown on maternity leave, the fact that harassment leaves women with fewer mentorship opportunities, the fact that many environments treat interviews like hazing, all these things add up to create aforementioned gap.
Your quote up at the top is the root of the pay gap. It's your belief that someone who works a reasonable sum of hours but then goes to have a child should be paid less. You believe that someone who takes time off for a reasonable work-life balance or a family emergency should be paid less. That attitude is bad for everyone, but it's especially bad for women in much of western society's current form.
And yes, there are still places where women DO get paid less for the same work. That is not done yet. And until it's so rare that it's unheard of, we're going to keep pointing it out.
