WOTC - Guidelines on medical fees

I asked this question in the Wisdom of the Crowd:

Should the Singapore Medical Association be allowed to set guideline for charges by doctors?

Here are the responses:

63 % - Yes. The guidelines are useful to tell consumers the reasonable charges.
26 % - Yes. The guidelines will protect consumers.
7 % - No. This is anti-competition.
4 % - Yes. Provided the guidelines are not mandatory.
