So the only difference in a totalitarian system is that it's faster in making decisions. The US would take longer to scrap user fees as we'd take longer to introduce them because we're democratic. Whereas a dictatorship can bake both ideas more quickly. As for the one-child policy, it would only be a matter of the majority supporting an idea to make it legal. Just consider the attempted cultural genocide of many First Nations in Canada over decades in our history, supported by a democratic majority. A democracy can be just as savage as a dictatorship can be benign. In the end, it merely depends on the government in power.
Democracy can be as savage, but things move much more slowly in a democracy. In a dictatorship, once the dictator is convinced the idea is good, it is implemented very quickly.
If in Singapore they want to implement the health care reform that Democrats are trying to implement in USA, I assume it could be done in less than a week.
Dictatorship has a few (very few) advantages over democracy and quick decision making is one of them.
Indeed, suppose as a result of use fees, cancer incidence rises in Singapore (I don’t know that it has, but assume). The dictatorship can pass a law mandating that every citizen must visit the doctor once a year (or once every two years, whatever) to get colorectal checkup, or to get a mammogram, Pap smear etc. If patients have to pay user fee to do that, that is their problem, not the dictatorship’s problems.
Suppose we implement user fees here in Canada and as a result there is an increase in cancer. No way we could pass a law like that, forcing people to visit their doctor. It will be against the Charter.
As I said before, there are things a dictatorship can do, that a democracy may not do.
