Re: It works..
Fatbergs are a product of our city sewers (dense population centres) and people carelessly throwing fat down the sink. This is cultural - many countries don't even allow toilet paper down the pan, it goes in a bin instead (Brazil). In Japan bidet toilets largely negate the need for it.
So, carefulness being a part of the social contract, and thoughtfulness in our infrastructure.
Let's be careful here and not talk in terms of extemes - the idea is not to allow everyone to become fat lazy coach potatoes, but to lead good lives. Building a house can be fun if you do it with friends and will enjoy the fruits of your labour. Useful work can make you feel good, doing shit work for low pay for forty hours a week doesn't.
