As a non-Indian who’s lived and worked in India for a few weeks or months several times in the past couple decades, ISTM from my limited knowledge that aspects of both positions are valid.
I’ve certainly encountered middle-class Indians who think that cleaning their toilets is “servants’ work” and wouldn’t do it themselves if they could help it. But I’ve also read that many middle-class families in the recent COVID lockdown, when their maids weren’t allowed to come to their houses, were doing all the housework themselves, including the scrubbing. So clearly it’s not some kind of insurmountable non-negotiable taboo against the very act of cleaning a toilet that’s operating here.
Just to throw in another data point for comparison, I’ve also spent some time living and working in the Netherlands, where I encountered the Dutch office toilet. IME, a fair number of non-Dutch people, especially Americans, are kind of grossed out by the Dutch expectation that you should clean your office toilet after you use it, if your use left any visible marks.
The typical American expectation of a shared restroom in a business establishment is that you use the toilet as necessary, flush whatever you put into the toilet, and try not to befoul the touchable parts of the fixture. But it’s not your job actually to scrub the thing, even if you left a couple smears in the bowl after flushing. Nor are you required to pick up and dispose of, say, a scrap of clean toilet paper that you accidentally let fall on the floor. It’s the janitor’s job to take care of any cleaning that involves touching anything in the restroom beyond the bare minimum required for your own use of it.
This attitude is widespread even among Americans who routinely clean their own toilets at home. But the Dutch in general have little sympathy with such squeamishness. If you left a mark in a Dutch office toilet detectable with the naked eye, then by golly, you better grab the toilet brush thoughtfully supplied by the management and get rid of it. You are supposed to leave a shared restroom after use not merely in a marginally tolerable state, but actually clean.
From a Dutch viewpoint, American resistance to performing cleaning tasks in shared toilets makes no more sense than some high-caste Indians’ resistance to cleaning their own toilets. Sure, in both cases it can be argued that you can get away with not doing it because it’ll be done by somebody else whose job it is to do it. But from the perspective of people who think it’s a normal thing to do, the resistance to doing it seems kind of dysfunctional.
