Actually, I'm surprised the question is still open and still has a nonnegative score.
What is the issue with the question?
I think the comments make the issues pretty clear:
- This is not an academic question; many careers require long hours for low wages during the early years. For example: bankers, lawyers, and doctors.
- This is similarly unrelated to any particular gender or race; single fathers in the West face similar pressures to what you describe (well, except for "periodic cycles" I guess). Indeed, some may find your assumptions offensive.
- Even setting aside these troubles, it's not clear what sort of answers are possible. Your actual question is "how do superwomen find time to deal with academic activities?" and the only possible answer is "they work hard and efficiently." (Though, I did think Wetenschaap's answer was excellent).
Is the main site intolerant to non-western?
If you search the India tag alone, you will find 77 questions, many of which are open. So, we have a pretty good record of handling non-Western questions (though our user base does seem to be predominantly western). I realize it can be frustrating to ask a poorly-received question, but I don't think accusing us of intolerance and bigotry is a defensible reaction.
