Which ethnic teachers? It probably comes down to more IQ than anything else.

IQ tends to map to wealth.

Asians and Jews have the highest IQ averages so unless they were being paid significantly less I'd put this down to the usual grievance anti meritocracy social justice bullcrap that the leftist activists usually push.

Academics in Ireland are hugely overpaid and underworked. A lecturer of mine, now retired, was head of the College of Arts. He is English, we sat in his office and gave every lecturer Friday afternoon lecture slots, in order for them to actually stick around. They all believed Friday was a half day. They all rock up around midday on a Monday too so they always have a long weekend.
Since this lecturer retired, my daughter goes to the same university, there are no Friday afternoon lectures again - across the board. Lazy f***ers who do sod all. There is no requirement on them to research or publish either, unlike other countries.
Irish lecturers earn 40-70% more and have only around half the workload of US or UK academics.
Mostly, they talk and lecture pure and utter tripe. It is all an exercise in shouting loudest about the latest academic trend.
No word of a lie, the EU has just given a lecturer in Cork several million to research rap music. I kid you not. I'm sure that will please Ireland's burgeoning homeless people.

This is the kind of thing that makes Brexit look correct. What a waste of 12million Euro. I was an EU fellow and Irish Research Council fellow and can tell you that it is an endless gravy train.
If you look at these again, and think of the titles, there is nothing at all of value there - to anyone. Even the most irrelevant academic could not say any of these projects are useful to society.

This says ethnicities so who is paid less? Travellers/ Gypsies or Asians and Afro-Caribbeans. What university in this day and age would get away with paying a black person less for the same job that a white person gets more for? This sounds like rubbish - academics love a drawn out grievance procedure and legal case. They also love a moan and flounce.

Footballers are paid on merit. Regardless of race. Does academia reflect this ? It probably depends upon what subject they teach.

English lit ? Arabic ? Theology ? Welsh language ?

I will say this - if you are a visiting African or Eastern European lecturer or professor, you will usually get wages better than your normal wages from your home institution. You would not get the same wages as a permanent member of staff would. And I would say - why should you?
