I'm noticing a reversal of social deference: -Then: Older generations had the cultural authority, and children were expected to conform. -Now: There’s increasing tolerance—and even privilege—granted to children (and parents), sometimes at the expense of quiet, order, or adult comfort. Hypothesis: This shift reflects a society aware of its declining birthrate, where children are becoming scarcer and more symbolically…
The generation that got too much authority will give the next generation more space (louder generation). Then the loud generation will create louder generation and authority will come back, etc.
It's just an example and I don't think the loudness is part of those properties but the abstract mechanism has been observed along few generation (I think this mechanism had a proper name but I cannot find it again).
