Sure but the regulatory barriers are so high it's not fiscally practical for a normal person. I can walk into a pharmacy in Mexico and buy a Z-pak for strep; even for a poor Mexican that's easily obtainable all without insurance or state care.

I make a good wage but in USA with good insurance it would take me a days pay for same here after passing all the regulatory hurdles and costs and being billed for a doctor and that doctors malpractice risk overhead etc ad nauseum.

What are the difference between the regulatory barriers in mexico and the us that result in such a large difference of out of pocket cost?

I'm not sure what you mean by high regulatory barriers. I make an appointment, the very next question is "do you have insurance?" When the answer is no they inform me what it will cost, I pay with a credit card at thet time services are rendered and thats all there is to it. Whats regs got to do with it?
