Should this essay be required reading for all Christians? YES.

But I'm sure the political conservatives among them would find a way to shoot it down (with Sarah Palin and Glenn Beck taking the first shots).
HOW DO CHRISTIANS BECOME CONSERVATIVE? (A Very Good Question)

EXCERPT: The most fundamental difference between progressives and conservatives is that question of which side you are on. Conservatives believe that the rich and powerful got that way because they deserve to be, that society owes its prosperity to the prosperous, and that government's job when they have to make choices is to side with those businesspeople who are doing well, because all good things trickle down from them. Progressives, on the other hand, believe it is the poor and those who are ill-treated who need the most help from their government, and that prosperity comes from all of us -- the worker as well as the employer, the consumer as well as the seller, the struggling entrepreneur trying to make it as well as the wealthy who already have.

...if you actually read the Gospels, it is clear that Jesus' main concern in terms of the people whose fates he cared about was for the poor, the oppressed, and the outcast. Comment after comment and story after story in the Gospels about Jesus relates to the treatment of the poor, generosity to those in need, mercy to the outcast, and scorn for the wealthy and powerful. And his philosophy is embedded with the central importance of taking care of others, loving others, treating others as you would want to be treated. There is no virtue of selfishness here, there is no "greed is good," there is no invisible hand of the market or looking out for Number One first. There is nothing about poor people being lazy, nothing about the undeserving poor being leeches on society, nothing about how I pulled myself up by my own bootstraps so everyone else should, too. There is nothing about how in nature, "the lions eat the weak," and therefore we shouldn't help the poor because it weakens them. There is nothing about charity or welfare corrupting a person's spirit.
