>>In fact, up till a few generations back, most Indians would be aghast at the unhygienic notion that one can have a toilet inside one's home!
Up till a few generations back, some one's home was clean because some lower class guys were cleaning up while the higher class guy enjoyed their hygiene. Or in other words this was at the expense of other fellow human beings who did all the clean up while one could brag about ancient methods of hygiene.
No civilized society would accept such a classification of people in the modern times. So a person is expected to clean their own mess.
You are right when you say
>>What we end up doing is comparing the apples of present day hygiene etiquette to the oranges of what is remnant of a hygiene system that has worked quite well in its hey days.
