Australia ranks ahead of the United States in:
OECD Better Life Index

Legatum Prosperity Index

Freedom House Index

However, none of these measures includes your important variable of how white is the population. Australia is becoming, like the U.S. and Canada, a country with a large Asian minority; and those Asians are as good or better than we Europeans in a lot of ways. They have intact families, raise their children well, obey the law, and they have strong work and save ethics.

My ranking did not have anything to do with how “white” they are. It is about how bad the government has become.
It has become much more socialist, much more restrictive, much more concerned with some sort of “restorative justice”.
Electricity is becoming more of an expense than mortgages, for many people.
A couple of examples:
You cannot carry a pocket knife, except if you can tell a policeman what “legitimate purposes you are carrying it for”.
It is easier to obtain a permit to have a rifle (which takes some effort) than to have a slingshot.
I cannot be sure the immigration of non-European types was the crucial key to the vote-power change, but it was coincident with it.
The rankings cited, as with all such things, are very subjective.

The Mathematical Association of America (MAA) is a professional society that focuses on mathematics accessible at the undergraduate level (Wikipedia).
The American Mathematical Society (AMS) is an association of professional mathematicians dedicated to the interests of mathematical research and scholarship (Wikipedia).
My impression is that the MAA is the more political (e.g., DEI) of the two.
