Who is more likely to be an optimist - the physiologically well constituted or the chronic sufferer? the powerful or the disadvantaged? Certainly there are pessimists among them all. I don't think there is a clear cut answer as to what makes an optimist. I tend to think that one who has come down the ladder in terms of social position is more inclined to pessimism then one who is born low on the ladder. One could say that some very poor people are the happiest people on earth, however their happiness is not necessarily synonymous with optimism. Some pessimists could be said to have found happiness. As a general rule, I would think that pessimists might be more affected by injustice - real or percieved - than optimists are.
