the gap is a result of personnal/family choices.
There is no such things as female payscale, it's illegal of course.
I tried to found out how they came with this numbers, because I knew that the hourly rate was the same for men and women, in any jobs.
And I found out that it was a totally dishonest social study, all of them. It's just politics.
The result of the Era we are in, minority sacralisation.
Here is how it is calculated: (exemple from a good friend of mine)
He's a doctor. Family doctor. He work long days and make 10000€/month.
His wife is a teacher. She makes so little money that they decided she will work half time only, then she can take care of the kids.
She makes less than 1000€ a month.
=>Women make ten times less than men
It's real, that's how they do the calculation. Check by yourself.
