This chapter seeks to make two principal points. The first is that upward mobility on the part of disadvantaged persons in the cities has been, is being, and doubtlessly will be, hampered by laws and regulations the manifest purpose of which is to make them better off. The second is that as our society becomes more sensitive to social injustices (real and imagined) it thereby becomes less capable of coping with certain of its problems; indeed, it increasingly confronts the dilemma that a good society, if it is to remain one, must sometimes do things that are incompatible with its goodness.
