take a 3rd world culture that openly beats women for centuries (to the extent that even neighboring countries had a problem with it.) and then suddenly educate women to modern western suffrage and then simultaneously provide the women with a western dating pool. (not necessarily white guys, but korean-americans who are seen as more successful, kinder, more educated, etc.)  korean women are just eager to eject out of korean culture. the men, don't really want to settle for other women- although some marry south asians.
