There are many wealthy Indians in India already - what India needs is a middle-class - i.e. people that have a roof over their head, with their basic needs taken care of and that are empowered to create their own wealth.
Maybe they aren't super rich but I am sure the napkin makers and the inventor are both doing better then they would otherwise and more importantly they are keeping the money in India.
Are you sure about that?
If every (menstruating) woman in your village purchases their sanitary napkins from you every month because you've got the one machine within 25 miles, you may have a compelling small business, especially when adjusted for cost of living and ease of labor.
