It isn't like that. If you want to call it stealing then I would be stealing from the whole of society not you specifically. I suppose you also think that I am stealing now because I am benefiting from a public education, I have a subsidised bus pass and I go to an NHS dentist.
If I knew someone who was evading tax I would not turn them in to the police just as I don't turn in someone I know who is claiming benefits while working - however immoral I find that.
Very well, you're not aiding and abetting.
You're also not
personally stealing from me. (in fact, since I think you're in another country you're not stealing from
me at all, but that's beside the point) What you are doing is delegating your desire to steal from me (figuratively speaking) to a group of people. So a better description of what is going on would be
conspiracy.
