A bureaucracy in Brussels is hardly necessary to enact simple pan-European tariff reductions. It is necessary, however, to begin building what globalism truly demands: a de facto European government, complete with dense regulatory and tax rules, quasi-judicial bodies, a nascent military, and further subordination of national, linguistic, and cultural identities.
Why should the people of England care what globalism "demands"?
Additionally they never specify the recipient of globalization's "unprecedented wealth". Why should it motivate the average UK voter if they don't profit?
