Who are those Vietnamese living illegally in other countries?

Hello everybody,

I think it was in this subreddit that I learned that there are Vietnamese people who live illegally in richer countries, in the west, for example. Now I imagine that it is a hard life in permanent danger of getting caught and with access to schools, doctors, jobs etc being a challenge without appropriate documents.

Now when I am in Vietnam I see people working, people on motorbikes, people eating or drinking in the street but I don't see much desperate poverty. Of course, I know the average wage is just a few hundred dollars and many people have more than one job but still I wonder: Who would be the typical Vietnamese person who would take the risk to go abroad and live there illegally? The grab driver? The waitress? Young people without children? People with good education? People without good education? People with relatives in the other county? People without relatives in other countries? Desperate people? Risk seekers? People who somehow get the opportunity to do it?

And what does the average person think about it?
