Are they wrong? Which is more likely to affect any given individual? Which country do you have the best chance of life, liberty and the pursuit of happiness in?
That metric is hilariously wrong. Consider a country with universal healthcare, but where only a single political party is allowed. You're much more likely to face medical issues in your life, than wanting to start your own party and being prevented.
Does that make the one-party-state more free than every country without universal healthcare?
In other words, by phrasing it as "freedom to live in comfort and safety", you are conflating comfort and safety with freedom.
They typically do so to affect change.
Change that may well be required, for example, to address problems in said one-party healthcare system.
