I predict a "girl shortage" among many of these Third World countries. The poor or rural girls are being killed or exploited; the wealthier, educated ones might eventually leave that society once they begin to question its values and their treatment. The poorer men, especially, will be affected, as the woman's "scarcity value" rises.
China is already getting a taste of this sociological timebomb thanks to female infanticide. Already there is an uneven ratio of men to women and "woman-trafficking" going on because a number of rural men can't find wives.
I feel sorry for the girls, but not these cultures. My feeling is sort of shared with the poster above, of "letting the chips fall where they may." Unless these societies wake up in time & start protecting their weaker members, they're all going to go bye-bye.
On the other hand if this ever happens in Sweden, I will stop shopping and marry.
