I am in my mid 50s. Still working and will have to do so for many years yet.
For most people the standard of living has got higher. But the middle class is much smaller. I still struggle with the idea of lots of things as being essential, because I still see them as luxuries.
Whether as a baby boomer life was better for you, or better for young people now, depends very much on who you are. If you are white, able bodied and in the middle class, lots of things were better then. If you are poor, disabled, black, have mental health problems, are LGB, things are better now.
My DP and I suffered violence and abuse when young adults, that the police did not give a jot about. I would have swapped a police force and better society that cared about black people, LGB people, etc, than cheaper houses.
The truth though is that in every generation some things are worse, and some things are better.
