For the most part, and even though I’ve done some of it myself, I think this sort of bashing of 
the Baby Boomers is over the top.
However, one thing about that cohort is true: they grew up in the time of greatest prosperity the nation had ever seen, decided that it was good enough for them – and only them – and then pulled up the ladder behind them.
That is the inexcusable part, and it is generational as far as I can tell. The stats show this.
That ladder-pulling I can’t grasp, as it harms their very own children and grandchildren.
Saying, “I deserve my Medicare and Social Security but my daughter and son do not” is the worst kind of selfishness, but seems very common – in statement or in action – in that generation.
Keep in mind that generational generalizations tend only to focus on a specific cohort of a generation.
Of course, I feel that way since I’m in a demographic no-man’s land but everybody loves benchmarking data to within 2 years of my birth.
At least in sociological research, anyway.
I’m familiar with that research and disagree with a lot of it since I think general societal climate (absent any specific event) matters to generational tendencies, with some bleedover on the edges mostly related to siblings present in family structures imparting older-generation values and/or climate perceptions.
But this is hard to quantify, so it’ll never be taken seriously. People measure what they think they can and claim it’s all that’s real, or can be real.
I disagree.
