> How much more evidence do you need to see that more liberty is better than less?

I guess a bit more than a subjective comment on HN.

Your username is apt and seems to indicate that your comment is not in good faith.

Neither the US nor the UK are libertarian societies. Both have substantial safety nets and large governments that work (mostly) for the common weal.

Yes, during the 20th century, western economies did vastly better than, say, North Korea or the Soviet Union, but China in the 21st century is the odd data point. They are neither fish nor fowl, not communist, not really capitalist, certainly centrally controlled in some aspects and bizarrely wild west in others.

"US and UK are libertarian"

Can you elaborate on why you believe this? I don't see any way that the US and the UK are Libertarian, unless the definition of that word is stretched massively.

Is this a troll account?

Between the username and the blatant false statement about the UK being libertarian this seems like a downvote account from Reddit.

Neither are libertarian by a long stretch, and your measure of "better" is a bit fuzzy.
