Your original question:
I'd argue that the children of the Greatest Generation, the Silent Generation, were not embarrassed by their parents, many of who were, by any reasonable definition, heros. I'd also say that Boomers saw their Grandparents as "cool." I know that I appreciated what my grandparents sacrificed and all they achieved. I've accomplished quite a bit in my life but I am acutely aware that their sacrifices made those accomplishments possible.
Those are my answers both in macro and micro. Feel free to disagree.
