Hmm it's easy to say the Poles don't want border controls because they all come over to be plumbers, but I suspect this isn't the reason. This is simply because since they're in the EU anyway, they are still entitled to work anywhere - as we all are - it would just mean them showing a passport on their way to a different country (which they have to do when coming to the UK anyway)
I'd suspect it's more because they've got a very long porous border with the rest of the EU, and unlike many borders which formed through history along topographical features, forming a natural harder to cross border, theirs was drawn up pinched from Germany![]()
It means its extremely easy to cross, and there's a lot of cross border economic activity between Poland and Germany, almost to the extent of that which exists between British market towns.
You have Poles who have bought homes in Eastern Germany because they're in such good condition, and in charming villages - the German government spent a lot renovating them once the east was liberated 20 years ago, but fewer Germans want to live there as the German economic zone is more to the west. Bit of a bummer to have to show your passport to get home perhaps.
Dunno though
I half wish we were in the schengen, just to make it easier to get around, but for very obvious reasons, this isn't possible. The whole idea of the schengen is flawed really, as it only makes it easier for crims. Can't help wondering if those responsible for this idea were driven less by logic, and more by "oh this shows we are the united states of europe innit, now lets have politicial union.................oh as long as we are in charge of course"
