It's all good.
I do understand what you mean by R&D... But I think that's more applicable to drugs or high end surgery.
The reality is that 3rd world countries still can't do certain procedures that require incredibly high tech. That's still being done in the US, and you have to pay handsomely for it.
But outpatient stuff, or procedures that have become mainstream (like bypass surgery or hip replacement), it's mind-boggling the price difference.
One of the major factors have to do with the cost of insurance for doctors/practices over here. It really drives prices up a lot. It's part of living in a litigious society.
