The reality is that most people are self-interested and not at all ulturistic about things. They’ll begrudgingly clean their own toilet for their own sanitary sake but that line of thinking doesn’t do so well with public places. Go into a public bathroom at a truck station or anywhere else that doesn’t have a paid worker to clean up the mess and you’ll see just how much people cooperate to keep it clean. Spoilers: they dont, because nobody wants to clean up after themselves let alone others germ filled shit stains and used needles. If there was some magical unicorn ulturistic person that hauled ass to clean up the place out of kindness of their heart/for the good of community the next dozen people would trash it up again out of pure apathy. Some people are great and upstanding members of society that go out of their way to improve things, most are stupid self-interested animals who couldn’t care less about their actions inconvinencing others and making enviroments worse than when they enter. Lots of jobs important to keeping places running and clean are shitty, hard work and usually in nasty enviroments. Getting a gold star on their upstanding citizen sheet isn’t enough incentive. Now I can totally see a UBI system where people who do voulenteer for these kinds of things get paid more than someone who doesn’t. But now were back to where we started, people getting paid more to do work that very few wants to do or has the skills to do.
