Earlier quoted context omitted.
Consumption is a terrible proxy for quality of life. It's also terribly USAian of you.
Not really. Europeans aren't some superior noble ascetics. People want to consume, and their demand exceeds their ability in practically all situations. So USians are getting more of what they want while most Europeans would jump at the ability to do the same. For the record, I am European myself
How much you can consume is also linked to how much space you have to use and store stuff. In 2015, 40% of the american households had three or more TV sets. I don't know anyone who owns three TVs here in Europe.
