I asked this question in the Wisdom of the Crowd:

Here are the responses: (38 Votes)

53 % - Large increase in fees charged by public hospitals, which are followed by private hospitals.
42 % - Failure of govt to control the health care cost.
5 % - An older population.
0 % - Our cost is still quite affordable compared to other advanced countries.
