Robert Wade is a New Zealander based in the UK - he's a professor of political economy at the London School of Economics, and he is a world expert on inequality.
A couple of years ago he spoke to packed houses on a lecture tour around New Zealand. He's back in the country to talk about how the growing gap in wealth and income are playing out on the world stage.
A recent Credit Suisse report found that the richest one percent of the world's population controls 50 percent of its wealth.
The gap has been growing everywhere but in northern Europe it hasn't being growing as fast as here. Why is that?
