About how many people in the USA do you think are on an insurance plan that doesn't limit what procedures they can get, and/or can afford to pay out pocket for whatever other procedure? Also, Healthcare companies are wildly profitable. If they were negotiating prices in the USA just like they do everywhere else, they would only be profitable. Woe is me.
