One thing about Singapore is that it has a very low unemployment rate 3.5% and a very high savings rate-- around 50%--  two things we don't have.   They have mandatory health savings accounts, and their population is working and therefore funding their savings accounts.

Their system has been a success, it appears, but it appears that their middle class is under pressure from competition from low-wage labor in neighboring countries.  Wages are down for Singapore's poorer workers.  This threatens their system of forced saving by individuals for health care and retirement, and also threatens Singapore's very low tax rate.
