Thomas Piketty’s Capital in the 21st Century was an unlikely bestseller in 2014.
Its account of how concentrated wealth shapes the world was so compelling that it went on to sell 1.5 million copies.
Now brought to the big screen by New Zealand director Justin Pemberton, it’s a griping and sobering watch, but with a few key ideas which could change our economic future for the better.
Justin Pemberton joined Simon and Phil to discuss the film, and what our future could hold if we don't close the inequality gap.
It's playing as part of the New Zealand International Film Festival. Go to https://www.nziff.co.nz/ to find your nearest screening.
