Majority, people that migrate to other country because of money... Where they can earn more and buy things that they couldnt afford to get while in their home country..
But mostly people that migrate end up with nothing because of their lifestyle... Also mostly they have low quality of life, especially the place where they live... They prefer to sleep in a room with 3 or 4 other people inside. They even use living room to set up a cubicle to sleep...
They earn and they spend since too much temptation which is hardly to control
