Interestingly, it has only been achieved by a handful of middle eastern countries because they have the natural resources to support its population.
I think a close second is Singapore where no one is left behind. But I classify it as a very desirable benevolent dictatorship.
So basically only dictatorships and monarchies can truly take care of its population. Looks like it’s a failure of democracy. Communism has proven to be a failure.
A tax should be imposed on the resources from the commons and redistributed to everyone. Taxation of human beings/human capital/private property is perverse. That seems to be possible in monarchies and dictatorships. Where do we go from here?
