There's a distinction between getting a "mail order bride" and looking overseas for a bride.
I know of a fairly tall, not fat, highly intelligent, New Zealander, a bald fellow, with a good career in computer programming, a couple years younger than me, who ended up married to a rather plain Korean girl in a Catholic church after moving to Korea.
If a guy with a high IQ and a good job who is tolerable to look at has to go overseas to get a wife, things are bad.
They're bad because of pro-feminist mindset of most religious groups and the total permeation of society with the immorality of tv and movies.
