Singapore also has a mandatory savings scheme which, although I doubt most of us would agree with it on principle, it does lead to higher savings rate, and it probably helps the country avoid spending a lot on welfare during an economic downturn (something normal in the West). It is also, more-or-less, a right to work country, and from what I remember reading the cost of hiring and firing employees is very low. It is also open to trade with other countries; something that it has to do for survival due to its size.
Also, with regards to mandatory savings, it is also a strong deterrent for people to stay out of the work force because it would eat away at their own savings. Their health system also, if I am correct, relies largely on Medicare-like system with large co-pays and deductibles.
The so-called Singapore Model is essentially a free market with a large government stick forcing people to behave more responsibly. I'm not sure how it can be used against Austrian Economics since it performs better than our economy because, although it is a mixed economy, it is more in the direction of a free market economy than ours. It is further evidence that freer markets perform better.
If it validates more government intervention anywhere, it is not in the economic realm, but in regards to responding quickly and forcefully to criminal and deviant behavior.
