Can A country or a person have it so good they don't know they have it so good?
Absolutely, yes. It’s a phenomenon often summed up by the phrase "you don’t know what you’ve got ‘til it’s gone." When things are going exceptionally well—whether for a person or a country—it’s easy to take the good stuff for granted because there’s no contrast to remind you how rough it could be. Psychologists call this "hedonic adaptation": people get used to their baseline, no matter how high or low, and stop noticing it. A country with stable governance, economic prosperity, and peace might not fully appreciate those things until they’re disrupted—say, by war, corruption, or economic collapse. Same goes for a person with good health, a solid job, or a supportive family; they might not clock how rare that combo is until it unravels.

Historical example: Post-WWII America. The U.S. had booming industry, a growing middle class, and no war on its soil—things a lot of the world couldn’t dream of. But people still griped about taxes or commutes because that’s just human nature when you’re not dodging bombs. On the flip side, someone in a war-torn or impoverished place might see that as paradise. Perspective’s everything, and it’s usually only sharp in hindsight or through comparison.
