At least from a talking point of view of millennials, GenZ, GenX etc. The differences these categories describe have nothing to do with the year they were born but with their age. The same issues you can read about describing given generation can be found in books and articles from 100 years ago.
People preferences change with age. You get older, get kids, get richer and you have different values and look on life when you are 40 and when you are 15. That is just life.
Treat people as individuals, not as a category.
