How effective can a boycott be on countries who do little to nothing about abusing women?

Here we are in 2011 and rape and murder of women is still something that is rampant in many countries. Aren’t we condoning this behavior by supplying these countries with goods, money and trade? We surely cannot go to war with all these countries but maybe an empty wallet and empty stomach may make their government think a little harder about turning a blind eye to this caveman behavior.
I know this is not a perfect solution because many will suffer, but aren’t they suffering already. I haven’t seen where giving them aide or money or trade has really changed the situations in these countries. The rich there simply get richer and the poorer still suffer at their hands. They just find other ways to justify their crimes to make it look more reasonable or just a rouge group. They know who these groups are and choose to do nothing because they want to keep the women suppressed.
Mother nature has always had a way of controlling human population through hunger and illness.
Shouldn’t we just let things progress as nature would allow so that our current cavemen go just like the dinosaurs?
Aren’t we just prolonging what going to happen anyway?
