No, most of us are not exactly well off. You will find far too many drivers, whole-seller, courier folks etc who are Muslim in India. The difference is, we can chose to live in parts of the country where our money goes a bit further than big cities. When I mentioned "business" I guess I should have also mentioned "self-employed" as well.
Oh lastly, like most of the self-employed folks and ur-organized and informal businesses I guess a vast majority of us are not paying taxes. Not that I am proud of it...
