I know of two people who definitely have mail order brides, both from Columbia. There’s a third person of whom I’m familiar that I suspect has a mail order bride (also from Columbia).
One is a skilled-trades electrician. Smart guy. He’s not shy about expressing it. Next guy is a production guy at a competitor. He spilled the beans. I’m just assuming the third guy is, too, since, well, how do you meet women from Columbia (tongue-in-cheek, my wife’s from Mexico, and didn’t come in the mail).
So, can I say that it’s “big bucks”? Dunno. But me knowing of two of them? Well, seems like a whole lot of people (relatively speaking) to me, who knows very few people.
