I know women get paid a lot less, the reason being that they do a lot less work.
As for them getting paid less for the same work, post your source.
Of course, it's no one's business what an employer pays someone except for the employer and the employee.
If it is inspired by racism or sexism, that is untrue.
And that women make less for men for the same work is pretty widely known.
No, it isn't. That's no one's business but theirs.
The only statistic I've heard is how much the average man makes versus how much the average woman makes.
