I have a unique take on this issue.
It is not the fault of the Boomers. It goes back to the Lost Generation. The degenerate culture that triumphed in the 1960s and 1970s which we call the counter-culture was the second wave of modernism. It was when modernism hit a critical mass in American popular culture which was made possible by the spread of television and the expansion of higher education after World War II.
The Baby Boomers didn’t create this self-absorbed, anti-traditional ethos which they have become identified with. It was already here trickling down from cultural elites and worming its way into the educated and professional classes in big metropolitan areas. This garbage arrived here from Europe in the 1910s shortly before World War I and has been snowballing since as far back as the 1920s.
As for the Boomers, Gen X, Millennials and Gen Z, the only real difference across generations is how far this ethos and mindset has put down roots and penetrated our culture. It has only gotten worse. The first half of the curve was the Losters, Greatest Generation and Silent Generation though.
