Our concerns about what we saw in Australia: an economy clearly tied to China has hitched its wagon to the tail of the tiger.

Healthcare is growing now at about 10 per cent per annum in the U.S. top line, versus 3 per cent for the economy. As someone with a sharp pencil and an eye for this kind of thing, this can't last.
