Is Unsustainable the new IT word?

I don't want to get all political, but I'm going to post a couple of links...

Cuba says their free health care system is unsustainable.
Canada says their free health care system is unsustainable.

So basically, Cuba and Canada both used the word "unsustainable." The cost is too much of a burden for their governments to handle.

I bet most people, Democrats, Republicans and Liberals alike, would agree that our health care system needs to be overhauled. But why in the world would we do something that other current governments say is not working for them?

All I can think is that those who don't know history are doomed to repeat it.
