Comparing profits from sales in a particular country to corporation tax paid in that country by a foreign company makes absolutely no sense.
Apple's tax avoidance schemes are in place to avoid US taxes, not German taxes or taxes elsewhere in the world outside the US.
I think Mr. Krach is right that global corporations do not pay their fair share towards global infrastructure and education. But the reason for that is not tax avoidance. The reason is that corporation tax, as it is structured today, is unfit for porpose in a globalised economy.
Corporation tax is based on the assumption that companies primarily use the public infrastructure of the country where they are incorporated. But for global corporations this assumption is incorrect.
So Mr. Krach is barking up the wrong tree, unless his main concern is US tax take. He should call on politicians to change the way in which global corporations are taxed.
