I don't think anyone democratically voted for enshrining tax arbitrage across the bloc - this is the Irish government, a massive recipient of EU subsidies, gaming the system.
As an Irish and European person, I want you to know that your comment is misinformed and misleading. Global tax avoidance and evasion by multinationals has no relation to the formation of the EU, and the Irish government are at a gigantic economic loss (not advantage) as a result.
