Examples include being unable to afford the high airfares for a big family. Mixed nationality couples who cannot return home together. People who genuinely feel safer here than at home.

Some have had multiple flights cancelled and cannot even get their money back. Your attitude is somewhat ignorant as well as lacking in empathy.
