But the real point is that: we should be constructing the best world we can in which people can thrive.
Measurements and metrics can be useful, if taken in aggregate, but we know full well that any metric that is used as a primary goal ends up becoming its own tyrannical destruction of the rest. (And thus, it's not surprising that money as the primary goal ends up being hyperdestructive.)
I don't want to "know who's better". I want to help people be able to be better.
