GDP being a weak and misleading metric has been known to be a factor from many decades.

It's just an easy and lazy measurement most can (or think they) understand.

Apart from money not being everything, it's also much "averages vs medians" (vs distributions) again.

People love using averages because they're a single number, and easy to calculate.

Medians are more difficult to calc, and distributions and percentiles are something most people are never taught, and it's no longer a single number which is easy to (artificially) compare.

Huh? Mean ("average"), median and mode are each a single number that provides a distinct measurement of central tendency.
