Consider this thought experiment: if Portugal has higher levels of human welfare than the United States with $38,000 less GDP per capita, then we can conclude that $38,000 of America’s per capita income is effectively ‘wasted’. That adds up to $13 trillion per year for the US economy as a whole. That’s $13 trillion worth of extraction and production and consumption each year, and $13 trillion worth of ecological pressure, that adds nothing, in and of itself, to the fundamentals of human welfare.
