What was the Cook's Tour version of the thesis?
West=western democratic republic plus capitalism (US style) versus East=Soviet satellite communism and centralized command economy.
The honest truth is I can't remember details, and it was written about 1974. At that time the West was clearly doing very well, but the East had a ways to go before things reached their bottom.
Work and study that I did on that project, cemented my belief in free markets, over centralized state owned command style economics.
Since then, unification introduced honest workdays to entitlement mentality Eastern Germans, for whom it was a shock.
BMW is an interesting study. They nearly failed in the early-mid 50s. Yet by the time of the US auto bailout, they looked at buying GM outright, but decided against it.
