Sometimes I feel like human beings in general despise when foreigners migrate to their country and do better than them in any way? Is this just in my head?

I could even remember when I was growing up my parents would say suttle things like. Don’t allow a foreigner to do better than you at school.

And i would also hear things like “Why do they allow foreigners to have radio shows and read the news”.

Is it just a fear of becoming a minority in your own country.

Or is it just ignorance.

Or a human survival of the fittest instinct.

I think this is a complicated issue. I could kinda see why people don’t like migration but then again, migration is a part of human history for ages. Even Jesus migrated from where he was born to another city to escape Herod.

How do you as an individual feel when you see a new arrival from a foreign land to your country or city that becomes as successful or more succesful than you ?
