I’d say it depends. If there are two people with similar qualifications, the Native Person would obviously be the more qualified due to their personal experience. But a non-native could be more qualified than an individual native person.

In the USA a good example of a bad choice was Ben Carson for Secretary of Housing and Urban Development. A disproportionate number of people in government housing are minorities and Ben Carson lived in government housing as a child and is a minority.

But Ben Carson was a surgeon. And not at all qualified to be in his position. He did a very middling job. Not terrible but obviously a better person could have been chosen. It was very obvious that his appointment was done because Trump wanted to throw Carson a bone for his support.
