Reconstruction is where this book, as do many in the area, falls short. Ehrenreich and English fail to offer up much in the way of a plan of action. The authors offer little in the way of suggestions as to exactly how society should begin to address the problems created by a marketplace mentality in which human beings are reduced to cogs in an assembly line. There's a clear and convincing argument that humans much change the system, but not a plan of how to change the system or even a particularly detailed vision of what the institutional structures should look like. (There's a newer edition out as of 2005, they may have added something to this effect.)
While I hardly think that Christianity or even religion is necessary for ethical action, I do think that Christian theologies that offer up a vision of what human society should be have a lot to offer in the way of reconstruction. Christian theologies from Liberation Theology to Silver Age Russian Religious philosophy are quite clear that humans aren't called to simply assimilate or "adjust" to a injust society but are called upon to improve it. And more importantly, progressive Christian theologies have something of a vision of what the world should and could become whether its called a Sophianic vision or a preferential option for the poor. Or, heck, just reading the hard sayings of Jesus seriously rather than listening to the self-proclaimed prophets of the religious right.
