"Almost every public measure and index"

For one, democracy and quality of life are subjective. Second, the other data points are cherry-picked.

Australia has a higher cost of living, a higher fertility rate, the Top Universities in the world 52/100 USA vs 4/100 Australia[1], the Top Medical Universities in the World 22/49 America vs 5/49 Australia[2].

And I could give you plenty more[3], but I think this proves my point.
