Tom Sine's Mustard Seed Versus McWorld is an essential book for Christians to understand the future effects of the developing global economy, and offers very practical ideas for Christians to offer Christ's "Mustard Seed" faith within it.
Here's a couple quotes from Sine:
"One of the essential conditions of economic globalization is that all businesses have unlimited access to the global labor pool to produce goods as efficiently as possible. This viewpoint insists that the employer has no responsibility either to the worker who loses his job in a car plant in Flint or to the worker who replaces him in Juarez. The employer’s singular responsibility is to show shareholders a profit. It is up to the free market to sort out the future for those in Flint whose jobs went south. And it is up the free market to set wages of workers in Juarez, even if the going wage is not enough to provide a decent way of life for their families.” (p. 59)
"Is the ultimate vision of 'something better' to be defined primarily in terms of economic growth, centralization, and efficiency, or is there something more?...Many of the advocates of this new global order define the ultimate primarily in economic terms. It appears that we are traveling into a future in which virtually everything in God’s creation, including human beings, will be reduced to a commodity and assigned a price…Deep down I think that most of us are not keen to see our lives and God’s creation reduced to an economic value, and McWorld is not our home. As followers of Jesus Christ, aren’t we sojourners in search of a better homeland?” (p. 67)
