if that was it's primary aim it is indeed a miserable failure, indeed funny to see it spelled out like this though.

the eu continent is a collection of states/countries, it was created to allow easier trade and movement. asians and arabs can apply to immigrate here just like anyone else, further down the road there is a possibility more countries that neighbor the eu could join us. which isn't a bad thing.

The US has a shadow government too. Is there any better way to avoid accountability?

That is a big problem with the EU in general, most decisions are made by faceless bureaucrats who have to answer to nobody but their money lending masters. The politicians are just there to sell those decisions to the people, and make things look legitimate.

Well this is one of many reasons why it's better to stay off the eurozone.
