Equity and new technology

I just saw this interesting talk by Ian Goldin, director of the 21st Century School at Oxford. He brought up quite a few issues, but the one that especially drew my attention was his point that we've seen vast improvements in the past half century but increasing inequity. As we move ahead, we'll see even more improvements and improved technology that we can't even imagine. There's a huge and likely danger, though, that that improved technology will not be evenly distributed, and that improved health technologies will only be available to the very top of the pyramid. Then, what happens with the bottom? Inequity in distribution of life-saving and -extending and -improving technology is not "fair," but it's also dangerous. I'm interested, then, to hear both your feedback on this issue and also ideas to increas equity.
