What, two wars abroad and a great recession not enough? Fight Club was written in a pre-9/11 world.
And that I suppose is my point, if you don't have some Nobel cause then what drives you on? If the world doesn't provide some ready made cause then your motivation has to be intrinsic, the only problem is that depending on what your goals are (money, fame, being a better dad etc.) you can end up feeling a little grubby about your choices especially if you don't succeed.
Whereas today, we don't have a great war, or any cause that makes us feel as we're part of something greater than ourselves. We have to come up with our own things to strive for, and sometimes these don't go as planned, or depend a bit on luck and circumstances. I.e. starting a startup or finding love.
