//The UK economy generally did a lot better inside the EU/EEC than it had previously, when outside it//
And the UK's main motive for joining the "Common Market" as it was then. And Ted Heath's willingness to sacrifice the livelihoods of Caribbean and Antipodean farmers in order to share the Eueropean economic resurgency. (Not to mention the Brennus sword chucked on the scale at the last minute of "negotiation" which destroyed the livelihoods of British fishermen.)
Relevance of that historic fact to anything now?
