> tell me which normal company (people) pay sub-1% tax?

Which company are you talking about? Apple's tax rate in 2019 was 16%. They paid $10.5 billion in corporate income taxes.

The problem is the bureaucracy of the EU can't manage to fix their tax laws. With 27 members of the EU, and a broad spectrum of economic condition among them, there will always be nations that will benefit from very low tax rates. There is no scenario where the EU will ever fix their tax problems. Ireland is set to become one of the wealthiest nations in world history because of their corporate income tax rate, their GDP per capita is almost 100% higher than Britain and France now and that gap will keep expanding over time. Ireland is going to give that up? Not a chance.

Hungary is at 9%. What's the EU plan for dealing with that? Threaten them? Sanction them?

Ireland is more likely to increase taxes for the general population than for corporations

A lot of Ireland's GDP is illusory, it's just money passing through Dublin on its way somewhere else.
