Not even that. The nations in the EU are guaranteed Taxation Autonomy by the treaty that created the EU in the first place. The Commission that is pulling his is the Antitrust commission. There is no trust question here.
So it is a fact that the EU does not directly tax individuals or corporations. Which was my point vs. the claim in the posted article. No need to go further than that.
Are the EU big-wigs and associated institutions the scum of the earth, ever over-reaching their purview? - yes, of course. A pox on the lot of them!
