Commercial air travel, like many other industries, is lubricated by cheap oil. Mr. Rubin, the former chief economist of CIBC World Markets, has now bet his career on a single idea – that the cheap oil era is dead and globalization is about to wither along with it.

Those unemployed airline workers could be looking for work – and finding it – in the revitalized factories of Southern Ontario.
