Why is Health Care Cheaper in India?

A $175,000 heart surgery in the United States goes for about $10,000 in India. What is up with that? Indian doctors practicing in the United States charge more than if they were in India?  Seems logical that one should consider going to India for surgery to save money. In fact, an employer would do well to encourage it. If employee Jones needs heart surgery, why not offer him the option of traveling to India with his wife, free of charge, pay 100% of all expenses, including medical expenses, and hand employee Jones a check for $20,000.
