Fun Fact: Nintendo's interest on their Cash Reserve is enough to fund Breath of the Wild

[SuperNova]

This reminds me of the Jane Austen economy where people literally lived off of the interest of their fortunes.
All the gentry had their money tied up in government fonts with 5% interest, so if you had a fortune of around 10.000£ you'd have a neat 500£ per year to live on.

(A gentry livestyle could be sustained at around 100£ per person, per year, but you'd be considered pretty destitute and probably only have a small house with a single servant. If you had less, you needed to *gasp* work to make a living.)

Uh yeah, that being said, nintendo probably isn't a Jane Austen heroine and probably invests their money more celverly, not just to combat inflation but to make sure these cash reserves actually persist.
