We never really know and the very fact that there are such words in the language as disappointment, regret, etc., is testimony to the pervasiveness and persistence of this feature of the human condition.
Thomas SowellFor society as a whole, nothing comes as a "right" to which we are "entitled." Even bare subsistence has to be produced-and produced at a cost of heavy toil for much of human history. The only way anyone can have a right to something that has to be produced is to force someone else to produce it for him. The more things are provided as rights, the less the recipients have to work and the more others have to carry their load.
Thomas SowellIn various countries and times, leaders of groups that lagged behind, economically and educationally, have taught their followers to blame all their problems on other people - and to hate those other people.
