So, the TL;DR summary of your post is “Things are much worse for women in the developing world than in the first (Western) world, so, Western world women should stop complaining”.
Given this approach, why stop at gender inequality? Why not apply this rationale to all things? Medical research, agricultural improvements, race relations, parenting skills, education, the list is endless. We should all just be happy with what we have since things are so much worse in the developing world, right?
You may want to reconsider your central premise.
