When people move to another country, economical scene and the emotionally aspect need to be considered. It is a fact that many people move to a foreign country but there are also a LOT of people who do not since they are afraid they will not get accustomed to the culture.
The quality of jobs, higher wages, more job opportunities are decisive factors while people evaluate whether to go to another country. In several countries, workers are not legally registered and bosses make them work ten hours or twelve a day. They are exploited and do not have any right. A wider labour market is another crucial factor. Work elements play a vital role while people consider moving to another place.
On the other hand, some people argue they would not move to a foreign country since they do not want to leave their families which are the most important thing for them. There are not many people who can move themselves with the whole family so they would be alone in an unknown place. Despite they deny wanting to move to another country, they think they would be much more relax and comfortable in another country if they are living in a stressful one.
My conclusion is that different people have different reasons for moving to another place to live such as higher wages or more job opportunities but, even considering these factors, they would not move because of emotional aspect.
