Price competition in healthcare (dental)

The Atlantic has an interesting article up about how more Americans are heading down to Mexico to get their dental work done. The reason can be seen below:

I am only surprised this hasn't happened sooner. Right now, taking advantage of price differences like this is mostly limited to people of means (free time to go to Mexico, money to get there, presumably paying in cash). But it's not just dental work anymore; cardiac surgery in India can start at just $3200.

Whether this delivery of better care for less money will ever happen within the borders of the US, of course, remains to be seen.
