None of this sounds to me like anything American conservatives favor. As in, there is no legislation that's been championed by major Republican leaders that would do any of these things and, in general, none of these measures comports with conservative aversion to government spending and regulation. And, yes, providers are regulated by a couple of entities. Now I sometimes hear U.S. conservatives analogize health savings accounts to Sinagpore's Medisave. But HSAs are a tax exemption for savings that are set aside for health care purchases; that's totally different from a mandatory contribution to a sovereign wealth fund. What's more, U.S. conservatives support tax cuts in general and tax cuts for investment income in particular. So conservative affection for HSAs seems to me to stand completely apart from whatever virtues it may have as health care policy. Note that in addition to the above financing mechanisms, the public hospital system also serves as a set of de facto price controls.
