With respect, I think you're coming at this from the wrong angle. In my opinion, availability of blurays, or whatever, has no correlation whatsoever with the general health and happiness of a society. In fact, the essay I linked specifically seeks to factor that out, on the presumption - that I share - that it is basically irrelevant. Are you a miserable, miserable man today because you can't get 2025's GreenRay UHD or super-ultra-holo-3d or the iPad 20 or whatever? Would any of those things make you a long-term happier person? Of course not. Technological knick-knacks do not bring long-term life satisfaction. Convenience does not equal happiness. You will not die with a smile on your lips because you own a retina display.
I'd advise you to read the essay I linked. It might change your thinking on a few things.
