In the tragic vision, individual sufferings and social evils are inherent in the innate deficiencies of all human beings, whether these deficiencies are in knowledge, wisdom, morality, or courage. Moreover, the available resources are always inadequate to fulfill all the desires of all the people. Thus there are no "solutions" in the tragic vision, but only trade-offs that still leave many unfulfilled and much unhappiness in the world. - Thomas Sowell
