I was in the park yesterday and two men were arguing about whether Norway should keep its oil in the ground. One said we're morally obligated, the other said we'd be naive to leave money on the table. They were both right and both missing the point — we're not having the real conversation, which is what we do with the fund in fifty years when it actually runs out. That's the conversation that matters. Everything else is just deciding whose grandchildren get to be angry first.
