Not sure where I drew that parallel. I think we aren't discussing the facist angle in this sub-thread.
What you are saying regarding Lindgren is correct, but the point is that the Social Democrats went to far, as they drew heavy criticism from even a loyal supporter. But then the party partially reversed direction in the 1990s.
Note that Ingvar Kamprad wasn't the only one to leave Sweden for tax related reasons in the 70-80s era. To name a few others: Hans Rausing (TetraPak), Stefan Persson (H&M), Ingmar Bergman, Björn Borg..
