When your job has been taken away by foreigners, what has been left behind will be all sorts of liabilities (housing, cars, wife, kids, parents, bills etc) that start haunting you.
If you can't handle all these stress at your own capacity, you may end up thinking of ending it once and for all. This is not new and it's going to repeat as long as there's not
enough jobs to go around for so many local sinkies and foreigners packed in this small little dot.
