> I've seen it suggested elsewhere that there is no saturation point, it's just that the relationship is logarithmic, and truncated logarithmic datasets look asymptotic.
If it's truly a logarithmic relationship (rather than asymptotic), this would imply that billionaires are an order of magnitude happier than everyone else.
The base of the logarithm does matter, but assuming base 10, a billionaire with an income of say $100M dollars would be 4 times happier than someone with $10k per year income which is pretty close to the floor in the US.
