I can only recommend that you have to base life decisions on your own experience, because it can differ dramatically.

I have an experience from which I have drawn some conclusions - I am an immigrant and many of my co-immigrants are convinced that the locals dislike them, they feel they are being treated unfairly, etc.

I was unable to square my experience with their's: surely they can't be imagining things, but at the same time I cannot be just magically lucky. Some of them are older generation, maybe things were different back then. Maybe, when they face difficulties they are more likely to attribute it to discrimination. Maybe some behavioural stereotyoes play a role - I don't know.

For a while I wanted to try a 'secret shopper' experiment, create two fake Linkedin profiles, identical except background- try applying for jobs with them. Never got round to it.
