The Baby Boomers thought that because they had 'changed' they had an opportunity to change the world. But they had not 'changed', they had simply been fed a load of mythologised moral and social simplicity and became disillusioned when the world turned out to be more complicated than they thought. they passed on a cynicism to their children and grandchildren that it didn't matter what they did, you couldn't change the ways of the world.
the new generations, 'X' and especially 'Y', are starting to realise that the Boomers sold them a bill of goods. they are starting to realise that while a few dedicated people might not make a lot of difference, doing nothing has certainly never changed the world.
