Volkswagen did over 380,000,000,000 in revenue last year. 30m is 0.0789% of that…

during the 1970s and 1980s.

That sounds a bit extreme IMO, you can’t really claim a fair trial when judging someone on the standards of half a century later.
AFAIK Brazil was a totalitarian shit show at the time, and that was not because of VW.
