1960's - Vietnam War draft, terrorist bombings in the US, race riots, Cuba missile crisis, ramping up the cold war

1970's - Oil embargo, massive (stag)-flation, "general malaise"

1980's - Recession, airline hijackings, multiple mid-East wars

1990's - Gulf war, another recession, leading up to massive tech bubble and crash

If you want to be stressed and disillusioned, there has never been a lack of options.
