Re: Tax Harmonisation
"Wont be long before there is a maximum and minimum tax rate each state is allow to set".
I would hope so too, then again the EU countries could have done it all by themselves long ago. The EU does not have that power unless it's agreed upon. Incidentally the USA doesn't have full power over the states either in many similar questions.
PS. "a maximum and minimum tax" is like from the pen of a politician, 100-0%.
