a.These groups are genetically almost identical to me. In the same situation as me, they would behave no worse than me.
Depending on which groups you're talking about this isn't completely obvious.
c. The other differences are memetically weak. Take the example of women's rights. Some developing countries have attitudes towards women's rights worse than any developed country, but they are not worse than past attitudes in developed countries. The same cultural changes that enabled us to free ourselves from these bad memes will enable them to free themselves as well.
I think you're looking only at the superficial memes. It's entirely possible that there are more subtly cultural factors, e.g., belief in progress, openness to new ideas, that are responsible for both our development of modern technology and our adoption of different attitudes toward women. Of course, now that the technology has been invented, they can import it without necessarily importing the memetic baggage.
Also, as Eliezer pointed out here even the most liberal person from the 18th century, say Ben Franklin, if transported to today would be so shocked by all the changes to prevailing morality that he might even conclude that the monarchists were right about man not being fit to govern himself. Well, Franklin didn't get to see the future so we live in a democracy today. However, the people in developing countries can see where our path leads, and they may very well choose not to follow it.

Well, that is basically the modern prevailing doctrine, though of course it's never spelled out so bluntly. The contemporary respectable opinion pays lip service to the idea of democracy in the abstract, but as soon as any really important issues are raised, it is considered incontrovertible that ...
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
