There’s nothing wrong with abundance and joy.
But being spoiled causes two real problems:
it makes it difficult to appreciate what you have. If perfect is the standard, it’s rarely met and never exceeded.
it leads to tantrums. Tantrums about sharing, about the lack of ‘more’ and about the endless poverty of comparison.
As a community increases in wealth, the number of spoiled citizens increases as well.
It’s often the acid that corrodes the magic that created the wealth in the first place.
Whining is a symptom, it’s rarely a cure for anything.
