Sure, it's a great idea to save money when money is being wasted, but I'm really skeptical of this new fashion of claiming that the US's worst problem is that our standards of healthcare are too damn high.
I don't think anyone is advocating lowering of standards. The Aravind Eye Care and similar success stories are all about innovation in the model of delivering healthcare. They excel in lowering costs through scale while ensuring high standards. The founder of Aravind was inspired by the process standardization of McDonald's and succeeded in replicating that in healthcare. The doctors at Aravind are actually considered to be among the best in the world simply because they perform far more surgeries than doctors elsewhere. Others like Narayana Hrudayalaya are replicating the model in areas like treatment of heart disease in India with great success. So, there's definitely room for process innovation which can improve the standards while reducing costs at the same time.
