skill issue

Let me guess.
Their both teachers, but one is a physics teacher whilst the other is English.

Ofc the guy who is teaching physics gets paid more

That's a joke right?

yes I believe in equal pay, but if someone does more work/harder work. they should be paid more.

the physics was an example of harder work. but this applies everywhere. A surgeon gets paid more than a nurse because of they have a harder job.

No it's what you think the diagram is
It's depicts ladies being paid less than men.
What you said had to do with the job itself.
I also believe in equal pay
I was simply asking if you had misunderstood the diagram

gap in job types, you get paid more for doing a more dangourous job. now which gender make the majority of miners? which gender makes the majoraity of tower repair?
