EU has a higher floor and a low ceiling: you’ll always have dignity and a decent quality of life, but it’s also harder to become obscenely rich because there are limits on how much you can exploit people.
Whereas, in the USA you can be left in the gutter to die or be given the tools to be the richest person on the planet provided your willing to exploit people.
Keep the EU citizenship to get that floor, come to the USA to be evil!
The problem is that while living in the US you run the risk of violent crime, mass shootings and general crime being obscenely higher than in the EU (or any other developed country).
Also you're always only one major health problem away from bankruptcy.
And your wife and daughter have less rights every day in some states.
Risk v Reward I suppose.
