Yeah, maybe. The GDR was under a whole different economic system, though. I mean, the UK and Ireland are pretty similar.
But I also think that if Ireland were in the UK and the UK were in the EU that probably everyone involved would be better-off -- not to mention all those not-UK not-EU British territories, like the Isle of Man and Jersey and Guernsey. Obviously a lot of people who actually live in the British Isles don't see things the same way, though, so....
