The statistics that show a wage gap always have the same flaws:
Doesn't consider amount of hours worked. (When accounted for, total women pay = 0.91 x total male pay, significantly higher than the overly-quoted 0.78. And this is only one extra factor)
Doesn't consider qualifications.
Doesn't consider their job.
Doesn't consider experience in field.
Doesn't consider lifestyle choices/ needs.
The one, single thing that it considers, it the total average pay of all women in all jobs against the total average pay of all men in all jobs.
So saying the "statistical evidence" implies that "women are paid less for the same work" is as stupid as saying we live in a patriarchy because women footballers earn less than men footballers... -_-
If I was ever to get really angry, and protest, a certain belief, I'd bloody do my research. Seems like they didn't.
