What would be the benefit for the EU to enter this shit race with the UK and the US?
Only companies would be the ones benefiting from this with yet another hub with lower taxes. It's a literal shit race if everyone starts playing it, and only works if few play it.
So good for the EU parliament to publicly denounce this and exposing the shit game the UK and US are playing. Basically they're both being cheats in the global economy - and you can't be both a cheat and a role model, that's being a hypocrite.
Are all the EU countries abiding by fair rules? No. But what will be the trend? To have more tax heavens in the EU or to start to purge them? All points to the second option.
