Question stolen from Twitter:
Everyone in the world has to take a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?

A society can only work in a world, where half of people are willing to press the blue button, knowing that they can rely on others pressing it too.

YES!
In safe society, a kid can play outside unsurpervised, since you know others will be willing to sacrefice themselves to help if anything happened to them.
In an unsafe society where everyone saves themselves, a kid cannot go outside alone.
That is the difference. (BTW, I had no idea just how bad of a place America was, until I learned, that "just walking outside" is considered suspicious)
Also, there are many "unsafe" societies where children still go outside alone so "can kids play outside unsupervised" isn't a useful metric.
