Don't forget that many of these foreigners are bringing their aged parents with them.
In some cases, one foreign IT "specialist" (sometimes with a fake cv) or technician is supporting a wife, 3 children and 4 aged parents.
But don't expect LKY to understand too much.
He only understands that his son is the best, his daughter-in-law is the best, his daughter is the best.
What he doesn't understand is that they are the best at being guniang and at being ugly.
He knows but it does not affect him at all, hence it is nothing of his concern.
