You have that arse backwards in terms of quality of life. The US is slightly ahead of China (Australia ranking of 6, USA ranking of 20, China ranking of 23, according to US News. Other organizations have lists with similar results):
Careful with studies. Note the things that make up "quality of life" by their metrics.
- Purchasing Power (including rent) - Safety - Health Care - Cost of Living - Property Price to Income Ratio - Traffic Commute Time - Pollution - Climate
And even that is kinda crap give their weighting criteria. There are 23 different indicators used to determine how safe or how dangerous a country is. These factors are broken into these categories:
- Ongoing International and Domestic Conflict - Societal Safety and Security - Militarization
The factors used to compile this report include:
-Number of internal and external violent conflicts -Level of distrust -Political instability -Potential for terrorist acts -Number of homicides -Military expenditures as a percentage of GDP
I think I'll stick with the US the way it is. Although, happy to visit Australia too. I'll try and buy everyone enough quality Australian craft beers to keep both natives and us tourists happy. I'll accept that the amount may be quite a lot.

If something on the internet makes you angry the odds are you're being manipulated
I'll accept that the amount may be quite a lot.
