> there is no reason why a Singapore system could not be done here.
I'm not saying it's impossible for the US to have a better healthcare system, I'm saying that looking at what Singapour has and then concluding that people in the states lack empathy is not only unfair, but also lacking in perspective.
> The United States is 50 small countries in one big country
Not only are each of the states bigger than Singapour, but they're different to each other and at the same time they're not completely independent of each other.
> The age of and diversity of a country have nothing to do with its healthcare system.
A system that has been in place for a longer period of time, tends to become larger, more complex and harder to change. Moreover, a society that is more heterogeneous will have a harder time agreeing on an issue. Also in a democratic country, the larger the population, the more people you'll have to convince in order to change the status quo.
