This is an interesting point of view, and it's important to note the difference between the MBA programmes at these schools and the MSc programmes (for which Germany is better prepared). However, anyone can see from LinkedIn and Xing that Reutlingen is not a target for MBB in the way that the ranked business schools are and, in particular, they recruit MBAs from schools abroad. Similarly, one can see that it is not the case that they only re-hire MBB alumni at these schools.
Nor can one take seriously the idea that it's a weakness that WHU and HHL keep their MBAs small. The MBA at WHU is very new, but even so it is obviously the case that employers' demand in Germany for English-speaking post-experience management degrees is limited. But the outcomes for those students are very strong, if they speak German.
