The finding by EC is that multinational corporations is taxing much lower that corportations in Ireland. If all Irish corporations payed 0.005% in taxes instead of 12,5%, then the EC would have nothing to complain about. However, if Irland did this, I doubt their budget would survive.

Equal treatment of everyone is a critical aspect to prevent corruption and an unfair market. Selectively lowering taxation is illegal, and I don't find that wrong at all.
