The EU is not a single entity that exists by absorbing sustenance from the periphery into its centre through some form of economic osmosis, you dribbling, raddled old buffoon, it's an association of member states that have joined a socio-economic club for reasons of economic betterment that has successfully grown over five decades into the world's largest, wealthiest trading bloc sustained by a constitution that upholds its principles of equality, fairness and social cohesion through the democratic process founded on a rule of law that applies equally to all.
