Millennials keep getting fucked.
Most western countries have also had a huge rise in living standards during the same time period meaning that the conception of 'economic hardship' is very different today to the post-war depression.
Anyone born 1914 through 1945 experienced either one or two wars plus the post-war depression.
Anyone born 1952 through to the early seventies lived under the cloud of imminent nuclear holocaust (read interviews with those who lived in those times -- especially those with first-hand knowledge of the Cuban missile crisis -- and you'll realise just how certain people felt that they were going to be annihilated).
I think the mid-seventies onwards are the earliest you can say that people have had a sense of existential stability.
