Have you lived where this is commonplace for any length of time? Have you done this in your own house? Having been born in a country where this was commonplace a few decades ago, I have a very hard time accepting it as a "sensible solution". It's just gross. I'd much rather pay for spelunking through my property taxes.
Surely you can pay for your own staff to clean the toilets. You're asking for infrastructure overhaul for what should be a waste basket with a lid emptied daily.
It is a good deal for me, I'm not denying that.
I put roughly as much credence in that statement as I would a smoker's that he doesn't really smell like smoke, or a dog owner's that his house doesn't really smell that doggy — i.e., none. I don't mean that rudely; I just don't think you notice the odour.
I too haven't had to unclog a toilet for reasons other than deficient toilets and/or excrement size for years.
What can do about it? I think that education is at fault. Most people in big cities does not realize how costly and important are jobs like sewer maintenance, garbage collectors, signal maintenance, gardeners, etc.
Without all this work cities will paralyze, the population will get sick or die, transport will stop working. etc. Without that work civilization instead of flourishing with economic growth and technology it literally will crumble into ruin.
Cities work because there is an absurdly large amount of people taking care of them. If it was a private endeavor there will be advertisements about their work everywhere. But, as a public service it is almost invisible. That is a shame.
Except most places I've been to and seen the practice have an open basket, I've never seen any soiled toilet paper in them and not entirely sure I'd like to...
I think about this in relation to modern society often these days. So much of the machinations that keep things running are invisible to the daily user.
Throwing toilet paper in a basket and taking it through the garbage route is a very sensible solution.
