It'll tell you: they are overrun by fat grazing hoards of herds of Karens and Kens.
When I encountered my first expats I didn't even know the word. That was in 1984, Subic Bay, Philippines. Most of them, retired Navy guys. In Angeles City, you'll find the retired Air Force. In terms of civilians, mostly Ausies—I guess because it's relatively close.
But in all cases, I admired these dudes. Same for my first visit to Thailand—Pattaya, 1986. In that case, lots of the expats were current or ex offshore oil-rig workers. In other words, just like with the retired military: men, not cucked beta-boy Kens.
