The crisis was 2008, in 2015 - almost eight years later and the gap between where we would have been and where we are is huge and not closing. The implied unemployment rate is very high, labour force participation is very low, and the increase in wages in the second quarter was the lowest in 25 years. Before this turmoil, the U.S. economy was in better shape than Europe or Canada, but not strong.

I'm writing from New Zealand - a country that decided from the beginning that the War was wrong, and chose not to participate in Iraq War.

In fact, for just about 1/6 of the cost of an Iraq War, we could have put the social security system on sound financial footings for the next 50 to 75 years. The problems can be managed - but not if we continue to fight this war for another 80 years.

The country that's been most successful at that is Norway. The more typical countries are those in the Middle East where a small group seizes those resources, uses it to buy arms to make sure that they can oppress the remainder, and you get these great inequalities. So Canada is among the better performing of the natural resource economies, but it's still not up to the best performing.
