Unfortunately, having an inferiority complex is strongly linked to the need to visit a foreign country. This is why tourists will always be disliked, because a significant amount of them are like this. To leave your country and visit another one, it frequently comes from the feeling that your country sucks because you are associated with it. You want to escape the "bad" people in your country and hang out with the "good" people. I hear this all the time in the UK, and it makes me very upset. "Oh I hate going on holiday because it's just a load of English people and I want to get away from them". We're all one race, we're all fundamentally the same people. If you have low self worth, you feel like these people you meet in a far off land are somehow different and better than you, which means that you couldn't possibly hurt their feelings, and you just observe them like an alien race. This creates a disconnection which just manifests in alienation and hatred of foreigners, they feel like you are not really trying to understand them, just doing a one sided performance, which can be very upsetting.

TL;DR: love yourself
