Seems to avoid even mentioning the desire of most of Europe to try and learn from what went wrong after the Great War. In 1918-1930 Germany was left so weakened by peace treaties that the seeds were sown for WW2.
Post-WW2 the allies felt that a Germany crippled would only bring future wars, and a huge co-ordinated effort to build a sustainable industry and economic growth was put into motion. Germany and the people of Germany should profit from peace. Part of this was the Marshall Plan, part the European Recovery Program.
This positioned Germany to have a couple of advantages, namely that the Victorian era mass production methods that had been pioneered could be discarded (but remained in place in a lot of the other European developed countries). In Germany these were fully replaced by WW2 era production methods as most of Germany's industrial capability had been destroyed or damaged.
Additional processes to limit industrial capabilities (the key method of which was limiting steel output of the Ruhr Valley, which acted to restrain all industry) meant that industry was incentivised to find a larger profit per unit rather than slimmer margins from more units.
Combined with not being able to maintain a military, Germany was able to invest in skilled manufacturing like no-one else were able to.
Over a course of 50 years this resulted in not just a modern manufacturing capability to be put in place, but for that to be at the very highly skilled end of manufacturing.
The reason so many of the mid-sized market leaders come from Germany can be traced back to post-WW2 policies to ensure that Europe could be at peace. Some of these policies were undoubtedly exploitative in the short term, but long term have achieved their goal.
