My take on it: the EU works by having state surrender part of their national sovereignty, and instead go for a set of commonly-agreed rules.<p>However, transcontinental treaties like TTIP and its ISDS provision would effectively remove a big chunk of each nation&#x27;s (and the EU&#x27;s as a whole) capacity to make decision which could be seen as &quot;business-unfriendly&quot;. Additionally, the fact that modern economies are so intertwined make them quite fragile (witness the way the financial crisis crossed oceans), which in turn mean less control by national governments.
