I haven’t said much about Piketty’s Capital because I haven’t read the book, and probably don’t intend to.

The r > g hypothesis is almost certainly true, as Piketty is just expanding on research done by other scholars that I have read.

What’s more interesting to me is that r > g seems to me to actually create the conditions for its destruction (inequality leading to eventual war, etc.)

I’d like to see more research on that. I would definitely read that.
