I am wondering.......

I'm wondering! Some of the things are tested on the third world first. For example, WiMax. They've identified many deployment issues with the technology before they deploy it in the developed countries, if ever. New medicine are launched in third world countries. It helps identify side effects with no legal costs. Human cost in the third world does not count. Surgery related equipment similarly follows.
On the other hand, some things are not tried on us first. For instance, electricity market deregulation, whereby a consumer can purchase electricity from a number of different retailers. Markets for trading power are established. As far as I can tell, the idea originated in the UK. Am I wrong?
Please comment on what you think placing some innovation in one of the above categories.
