I'll give the pod a listen, I trust Lyn to be better informed than me, but I belive their government subsidises practically everything so net net inflation is less bad.
I also believe Japanese workers are not living a great life. Long hours at work, low wages, no time or money to start a family. People who can save in dollars.
For an exporting economy they perform horribly, I would not look at Japan for inspiration. Especially if the intent is to support lower social classes.
But maybe I have things to learn.
