First, the author made a huge mistake when talking about GDP. Her comparison used absolute instead of per-capita values. India and Canada may produce the same amount of wealth, but India has 35 times more people. Of course per-capita GDP doesn't fully capture quality of life, but it's easy to measure and hard to fake. That's why it's used.
Most people make mistakes when it comes to balancing work and leisure, but to claim such mistakes are killing us is preposterous. People in developed countries live the longest, healthiest lives in the history of humanity. The nation with the longest life expectancy is the workaholic Japanese culture so disparaged by the author!
Many people, especially in technology, say their productivity is changing the world, and this is irrefutable. But no one seems to know what they’re changing it into, because no one can measure the world. When no one can measure the world, how much can it really exist?
This really irks me. Measuring and quantifying something is a prerequisite to optimizing it. Maybe a lot of people are measuring the wrong things. Maybe they're missing or underweighting a factor. Maybe they just have different preferences than the author. But to suggest that the entire enterprise is bunk is to disregard centuries of progress across a dozen fields of study.
If money doesn't make you happy, then you probably aren't spending it right.[1]
