The most important question any society must answer is: How will we make good people?
That is the question Judeo-Christian values have grappled with. There are many and profound theological and practical differences between Judaism and Christianity. But in the American incarnation of Judeo-Christian values -- and America is really the one civilization that developed an amalgamation of Jewish and Christian values -- the emphasis has been on individual character.
One cannot make a good society if one does not begin with the arduous task of making good individuals. Both Judaism and Christianity begin with the premise that man is not basically good and therefore regard man's nature as the root of cause of evil.
This may sound basic and even obvious, but it is not. In the Western world since the Enlightenment, belief in the inherent goodness of human beings has taken over. This has resulted in an increasing neglect of character development because evil has come to be regarded not as emanating from human nature (which is essentially good) or from morally flawed individuals but from forces outside the individual -- especially material ones. Thus, vast numbers of the best educated in the West have come to believe that "poverty causes crime."
Now, while no one could possibly refute the argument that starving people will steal bread for their families (an act that is morally defensible), the argument that poverty causes crime posits that when poor people in America commit murder and other violent crimes, it is because they are poor.
This is irrational dogma, as much a matter of faith as any theological doctrine. Two simple facts illustrate this: First, the vast majority of poor people, in America and elsewhere, do not commit violent crimes. Second, a large amount of crime is committed by the middle class and even by the wealthy. Neither fact prompts the "poverty causes crime" believers to rethink their position.
They need to, however, not only because the poverty-causes-crime thesis is so demonstrably false, but because it prevents societies from making good people. When society blames evil on forces outside the individual rather than on the individuals who perpetrate evil, society will work to change those forces rather than work to improve the character of individuals. That is a key to understanding why the left constantly attempts to radically change society -- how else make a better world?
