Human beings feel the pain of loss roughly twice as acutely as the joy of gains. Find $100, you're up 1 happiness point. Lose the same $100 and you're down 2 happiness points, even though you're in the same absolute position. It's called loss aversion, and it makes sense evolutionarily because it spurs us to strive for more, which helps the prepared survive.
But what happens when we're surrounded by prosperity and abundance we weren't wired for? We adapt. Fast. There's a term for this: hedonic adaptation. We get used to the good stuff quick, and our baseline for "acceptable" keeps rising. One can imagine this taken to an extreme, where every harm is removed from the developmental path, and the ways in which this would distort our sense of what is tolerable, what level of discomfort is acceptable, and who or what should be blamed when our expectations aren't met.
The Stoics understood this better than anyone, and in some ways it's their starting point. Expect nothing and you will be content. From our modern perspective this seems extreme, but we can at least experiment with lowering expectations to the point where we accept that some discomfort is inevitable. Suffering is an inescapable feature of life. In the face of it, the only noble choice is to endure it. And with some luck, courage, and compassion, hopefully we get to endure it together.
