I completely agree with your point about these technologies only being available for the rich. This is normally the way these things go at first but after a while there is a benefit to poorer countries as medicine is generally copied and then later sold for a fraction of the price as generic duplicates of the designer brand name pharma it was originally released as. The healthcare system in America definitely needs a lot of work and in many cases I believe Americans fund a lot of this research and development as they pay through the roof prices for medicine and healthcare. I went to a dentist in SE Asia and paid 20$ for a new filling. This same service would have cost me over $400 in the USA.
