I think the angst with "boomers" is due to the fact that today's culture and the environment and modern science points out that we, all of us, should act in a better way to our environment. However a lot of older folk seems to think that can reasonably hold onto the prevailing view that existed when they were born rather than confront reality.
Young people today have an eye's open approach to the disasters that are coming and a lot of the responsible people are going skip out helping with the bill. The anger is understandable.
