I haven’t looked into it directly, but when the media looks into it every time the tax lists are released (yes, anybody can look into anybodys tax returns) then many are shown with zero in both columns.

Others move to different countries to get away from our taxes. I guess it is because they are’nt rigged in such a way that they can hide their assets or do deductibles like that. But I don’t know how the countries they move to work taxwise other than that it pays off for them, or they wouldn’t keep doing it.
