“leave them be and don’t butt in”
They are committing an illegal activity, aren’t they? By not paying taxes, when they should be, they are breaking the law. By not paying taxes when they should be, that means everyone else’s taxes are just a little higher than they would otherwise be (especially if there are “thousands” doing the same). If you saw someone robbing a store, would you say “leave them be and don’t butt in”? They ARE robbing the store – your store, my store, everyone’s store. Ism’t there a moral obligation to society, and the rest of your fellow taxpayers, to report them? If you don’t think they should be reported, then I hope you never complain about how much you pay in taxes . . . . .
