"Over and over again courts have said that there is nothing 851*851 sinister in so arranging one's affairs as to keep taxes as low as possible. Everybody does so, rich or poor; and all do right, for nobody owes any public duty to pay more than the law demands: taxes are enforced exactions, not voluntary contributions. To demand more in the name of morals is mere cant."[1]
Rather, it is the governments of the world we should be going at if we want this behaviour to change. But then again, it is always easier to find a fat scapegoat with a shiny appearance.
