The Paradox of Progress
As society advances and major problems are solved, our threshold for what we consider a problem lowers. In the absence of significant hardships, our anxieties tend to shift towards more trivial matters. This creates a dynamic where, despite objective improvements in the world, people may not necessarily feel more at ease.
The Inevitability of a Minimum Stress Level
Most individuals and society as a whole appear to operate with a baseline level of stress. Once a problem is resolved, the focus of anxiety simply moves to the next issue, regardless of its comparative triviality. Even in a utopian scenario of perfect wealth, health, and peace, it's likely that grievances, albeit minor ones, would still exist and occupy our attention.
The Phenomenon of "Concept Creep"
The definition of a problem(s) expands over time. What was once considered a normal part of life can be redefined as a risk, and less severe instances of a risk can be recast as major issues. This can create the illusion that the world is deteriorating, when in fact, our standards and definitions have simply changed.
