Grabbing dodged taxes from corporations is somewhat arbitrary, in that it doesn’t happen because republicans keep defunding the IRS, which is a major issue because nabbing tax dodging corporations has a massive return on investment.
If Microsoft is getting busted, it’s not arbitrary. They just dodged their taxes poorly.
As an AnCap, I believe that involuntary taxation is theft, however, I also believe that each individual must focus on their own benefit. I also believe that these large corporations were largely built up and propped up by non-trivial amounts of public money and other forms of government help to begin with.
As I don't own any Microsoft stock and I don't use their products and I stand to slightly benefit (in my career) from them having less money, I don't have any moral issues with this SEC filing.
