Why live in a county you hate?

Why live in a country where you're surrounded by people you hate?

Why not move to your ideal country or return home?

What's holding you back?

@OP
many people living in Nigeria hate the place like a bad rash.
many people live in the US or Europe but only stays there because of the economic/reliability situation.
life is not straight forward, you cannot get ALL what you desire in ONE country so, many people choose one thing over the other.
some people live in some country TEMPORARILY in order to achieve their goals/dreams.

1. false expectation thinking that the grass is green on the other side. e.g cost of living, no job after much applications, cultural shock, home sickness etc

2. Lack of integration due to hostility of the people in the host country, weather, language, food etc

3. Family reasons tieing you, maybe having kids in schools and partner who work, its not advisable to just uproot them from their comfort zone to another place it will be difficult for them to integrate, especially when you have to job or financial income possibilities waiting for you.

4. Working on a contract, and you need to fulfil your contract term before leaving, or if you are a student.

It is always like this, people will always have one thing to complain about wherever they are, no where is perfect. I have lived in Nigeria, and I complained about it, I lived in scandinavia and I also complained about it there (especially the weather and lack of social life), I live in France now and love it here, I lived in Slovakia and loved it there, I lived in Austria and I dislike it there, even Netherlands was my worst nightmares. Now I am in Nigeria and I felt at home here. I couldnt leave Scandinavia when I was there because I was studying there, but I vanished after I finished my studies.

Different strokes for different folks.
