A lot of us don't want to be quite that serious about world problems. Our life is there to enjoy, not to be an eternal dissident, eternally unhappy with how things are and with the state of mankind.
It is hard enough to make a plan for how you are going to spend an evening with somebody else. So to make a plan for how you are going to behave in 25 years seems based on a view of life that is incomprehensible to me.
