When I was younger (and this may still be the case in many places), there was a fear within the immigrant community - one day we will be kicked out, told to go back home.

This started decades ago from when the labourers came over to earn money with a view of returning "back home". This meant that they saved up money and sent it back, maybe even built mansions there, to eventually return to. They lived more affordable lives here - if they were going to get kicked out or leave voluntarily, there was no point building a future here.
