Chances are it's something else.
It also has functionally infinite land, weak neighbours, incredible energy resources, isolation from any other world power, a (relatively) egalitarian culture, and the single biggest patch of good, arable land on the planet.
No shit workers get paid lots in such a productive piece of territory.
And I mean Canada has all those same things and wages are much lower.
Canada has lots of land, although it's generally much colder, less fertile, and just worse. They have oil, only it's thousands of miles away from the economic centres. They have arable land, also thousands of miles away from population centres (also far inland). And they border a hyperpower who could destroy them in a glance.
odd to hear reliable Chicago-School-of-Economics "facts" spoken with such confidence, while ignoring the change of local roads to superhiways, and 100 local retail stores closing at the same time. The very nature of the consumer transaction is changing. Economic analysis at the Nation level says that daily spending by consumers is the large majority of economic growth, especially when subtracting pure-government spending programs in the analysis.
Where are consumer transactions taking place? Involving what number of ordinary jobs? Consider that in the last five years, basically all retail clothing in New York City has closed. Are Milano or Rome different?
There are seismic, continental changes in economy that are not addressed by simple supply-side one liners.
