I mean, my first reaction is to go through it with scissors and point out all the stuff he leaves ut that would complicate the picture, but it doesn't really matter. The Junker's manorialism was destroyed by the Soviets in 1945 and besides West Germany dominates the new Germany politicly and economically.

And his political and economical analysis of the re-unification with West paying for it all misses the Western economic elites taking over the ownership in the East and the East role in keeping the value of the currency down. And so on.

There is probably East-West splits in Germany today, but it is more reasonable to look at re-unification than an economic system that was abolished eighty years ago.
