The problem I find with these global taxes is not the arbitrary percentage set but the agreement and collaboration between countries that implement it. Some specialize in offering tax incentives in differing sectors (i.e. Ireland with their innovation tax). Some are very lax on enforcement or keeping a good eye on things (i.e. Switzerland). Are they really going to scrap that for this global tax if there is high likelihood that not everyone will play ball?
If you only have a subset of countries on the same page, the accounting firms will definitely exploit that and move the wealth away from them, avoiding the tax. I just don't see this working at all any time soon, period - too many corrupt states in play at the moment.
