Stupidity is a polite word for it.

The European Union is not about cooperation for protecting the best interests of Europeans; it is about turning the entire continent into a Multicultural theme park while the natives get culturally deconstructed and demographically crushed. The EU is a large-scale social experiment conducted on hundreds of millions of people. It is not about economics of scale, it is about stupidity of scale. The EU system corrupts virtually everybody who comes close to it. It cannot be reformed, it can only be dismantled.
