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.

log(100,000,000) is 8

log(10,000) is 4

That doesn't seem to be 4 times as happy.
