I am not all that familiar with Singapore's health care, but just a cursory look at Wikipedia reveals that it's not really that much market-based, it looks quite similar to most European countries, really.

This can be expected under my model, too. The monopolistic prices depend on the demand curve, which depends on the level of wealth.

Private spending constitutes a larger portion of healthcare spending in Singapore than in the US. Also, much of that private spending is out of pocket:

Which is very unlike the US, where, as a result of government intervention, spending through insurance companies is the norm.
