Insurance cost - medical - do you think it's buffet style like what Min. Ong said? And do you think doctors are overcharging?

If the reported is factually true, it's a serious problem - because the medical cost and insurance will always go up - and then become very unsustainable for us, the consumers. I wonder what can be done? And if this issue can eventually be solved by govt alone... since Insurance + Doctors (private) are profit making...
