This is a clear display that we need free trade, sensible economic polices and a common ground of what humans need to thrive. "Sovereignty" is overrated.
For example, for the US to have a chance in the EU, it would first need to fix its YOLO fiscal policy of sustained 5.5% debt/gdp deficits.
We shall see in a few years as US's debt balloons and the average American becomes pseudo-slaves from a few overlords... to see if the EU is really bad as some Americans believe it to be.
