Cost

You may say as a taxpayer (and probably one of the heavily taxed few in this city), I am entitled to enjoyed such kind of medical welfare.

That's true, but, my question is: Is it a good system to deliver medical welfare?

Let me explain in a convoluted way:

Consider the scenario of the government general clinic. The charge is low, but it always takes a long time to wait before you could see a doctor and get the treatment. In other words, time is the currency of payment. For people who are poor or earn little, they could afford to wait because time is their only resource with an abundant supply. In contrast, for the rich people or working middle class, time is precious; they would rather pay for a private medical care to save the time.

PS. The same strategy is used in the delivery of many other welfare and benefit to people in need - from supermarket discount coupons to special offers by political parties (蛇齋餅糭).
