Re: why should the coumtry in which the item is sold enjoy the biggest tax 'take'?
Downvotes you are getting for several reasons probably.
1) The Apple fanbois don't like to hear that Apples tactics and ethics are being questioned.
2) The Aussies don't want to hear that they shouldn't get a piece of the Apple pie and maybe (fat chance) have their personal taxes reduced.
3) And probably this is a biggie... it's sheer emotionalism and nationalism at work here.
My rather simplistic view is that any country that is managing to extract any tax from a corporation should be grateful. Otherwise, corporations will country shop and find a better tax deal somewhere else. Yes, there are taxes being paid by said corporation to a given country: income tax for the troops, levies for benefits (such as Social Security here in the States where they match the employees amount), property taxes, etc.
Let the downvotes flow... companies are only people legally. The people in the company and who invest (there's some right bastards) in the company are the real people and it's not the workerbees who make the policies or decide how to maximize the profit for the investors.
