I critique market-based medicine not because I haven't seen its heights but because I've seen its depths.

The idea that some lives matter less is the root of all that is wrong with the world.

The idea that because you're born in Haiti you could die having a child. The idea that because you're born in you know Malawi your children may go to bed hungry. We want to take some of the chance out of that.
