Ireland isn't stealing from other people by changing their tax policies to attract business, that isn't theft by any stretch of the imagination outside of a libertarian one that posits all taxation is theft.. and you haven't answered my question: Why should Ireland change their tax policy to benefit other (much larger) governments?
It's fairly insulting that you've described the Irish as thieves, something Europeans have done for centuries, just because you want more tax revenue for other, much larger, governments.
