Boo hoo. Tokyo has no public trash cans and it is immaculate. The people there just care about the place they live in and don't burn shit to heat their houses.
In India, dung is used as fuel, sometimes out of necessity, sometimes ritualistically.
Politics in india pits ethnic group against ethnic group, caste against caste, in order to keep power and accomplish as little as possible. The economy is improving, but it appears to be stratifying, with radical divergence between the lifestyles of the richest and poorest. The wealthy are able to live in bubbles of luxury private development, blissfully unaware of the suffering just outside the gates. 
I'm bringing a lot of baggage, coming from a country where labor isn't cheap and the population isn't over a billion, but there is something to the value of human life here that I thought was universal. Maybe the expectations flip around when there are so many people that it would be cruel not to offer more garbage pickup jobs.
That smells a bit like a broken window fallacy though.
In the distance a herd of goats crossed the piles and paused to eat every so often, so I guess there's that.
Just need more people to push back against things like driving on the sidewalk, queue jumping, and blatant garbage dumping. Sometimes I do and the offenders generally listen or are shamed to stop for at least a bit.
Public infrastructure in India ultimately derives from the people. India has had 60+ years of independent, democratic rule. Blame for the lack of public infrastructure can't even be shifted entirely onto the colonial rule: India had some of the earliest hydroelectric power stations and pretty good rail infrastructure set up during that period.
Different cultures assign different values to various things. India collectively has not assigned a huge value to public hygiene. This is evidenced by things like the paan chewing and spitting mentioned in this discussion. This is socially acceptable in most parts of the country.
Slowly, things may change.
Am I the first person to have that idea?
But they didn't abolish trash cans (or better, they replaced them with a metal ring and the bag stays visible)
If the world and its manual processes were programs and code, these stories would be front page of the The Daily WTF.
Like, why not just do away with all those pesky municipal services people pay taxes for? It'd be so much easier.
Without the bins in London, there was close to zero "clutter" in underground stations. That makes it much easier to monitor for suspicious packages.
