Isn't USA even worse? If you move as US citizen to EU, you would need to pay bot h local EU tax and USA tax right? (I am not a USA citizen, this is legit question)
You're probably instead thinking of income tax, which the US does levy worldwide contrary to virtually every other nation on Earth and is, I can tell you from personal experience, not fun. There is a a much narrower exit tax for US citizens who wish to actually give up their citizenship outright (not just move out) but that generally only comes into play for anyone with $2 million or more in net worth, and exists probably to discourage tax evasion, to my understanding. There is truly nothing remotely like the "you have to pay us if you own 1% of any LLC anywhere and move out" approach Germany has.
