"The Older Generation (TM)" have been getting accused of becoming small-minded and bigoted since time immemorial. Which has made me ponder on it a bit, so please, bear with me as I explain my thought process
!
So, broad brushstrokes and sweeping generalisations incoming ...
Let's compare two people aged 60 and 30, just because it makes the numbers easier. There have been massive changes in the last 10 years. For the 60 year old, 10 years are only a sixth of their lifespan, and they have 50 years of memories pre-change. They therefore still regard the last 10 years as 'not the norm'. For the 30 year old, it's a third of their life and they have only 20 years of memories pre-change, so the last 10 years are very much their norm.
Memories can become rose-tinted, so the pre-change time becomes 'better times'. For the 30 year old, those 20 years of rose-tinted memories is childhood, teenagehood, uni / first job, social life. Basically the time when you're quite focussed on yourself rather than paying massive attention to how the world outside your immediate circle works. This makes the post-change even more of their norm. For the 60 year old, those 50 years of memories are going to encompass the more recent memories of work and raising a family and building a home, dealing with schools, watching their offspring enter adulthood, worrying that it's harder to get a job than in 'their day', housing so much more expensive than in 'their day'. Which reinforces the rose-tint somewhat!
Then add in that most people really don't like change, never mind massive and rapid change. The 30 year old is genuinely less aware of just how massive and rapid that change has been, because it has effectively been their whole adult life. The 60 year old is acutely aware of how massive and rapid the change has been simply due to having been an adult in the pre-change times. They have something to compare this post-change world with, and the downsides will be very apparent whilst the upsides will have slipped past silently.
So, although the 60 year old and the 30 year old are looking at the same world, they will inevitably have different experiences of that world and that will colour their opinions of where the world is now going. The 60 year old feels the need to 'warn' the 30 year old because in their opinion the 30 year old is sleepwalking into ever-accelerating uncontrolled change that will give them an even worse life than what they had and what the 30 year old has now. And this is what the 30 year old sees as bigotry on the part of the 60 year old.
Please pick my thought process apart. I said up-front "broad brushstrokes and sweeping generalisations incoming" so pointing that out isn't enough!
