The catch being of course, I can't find very concrete data on how many such schemes are "proper".

OECD data (source->alt) shows that *collectively* the US has a healthy mix of equity and non-equity, but how that is distributed... 😬 The 401k system requiring active involvement does not bode well.

Part of what makes this "Numbers are good, why are you not happy" economics falls so flat is that it combines vastly different groups of people in an attempt to get metrics.

Yet "Inflation" as a single number doesn't mean anything when there is no single basket of goods shared by everyone. 😐

3D graphics? You must be misremembering.
