The Huffington Post writes, "more than half of U.S. wage earners made less than $30,000 last year, according to an analysis released by the Social Security Administration on Tuesday." (See info graphic below.)
I think it's no longer controversial to say that the economic system is broken. At some point, the great machine that is pumping the resources of the many into the hands of the few is going to start having crippling costs for everyone.
The solution is the mind of Christ. Paul says this: "Let each of you look not only to his own interests, but also to the interests of others" [Phil 2:4 ESV]. This is the beginning of the mind of Christ, that joins him in becoming the servant of humanity to enjoy and deploy the power of the resurrection to the glory of God (vs. 5-11). Our economic system needs a resurrection, and Jesus knows exactly how the church can bring one.
