Many East Europeans (Romania, Bulgaria, Slovenia, Hungary, Slavakia, Czech) who were intent of migrating for economic reasons have in many cases already done so. Poles, Slovakians, Slovenians and Czech's generally migrated West and North West, Romanians, Hungarians and Bulgarians have generally migrated South to the Eastern Mediterranean areas where language, religion and culture have many similarities. Likewise British and American economic migrants have migrated to where well paid work was to be found such as Middle East, Far East, South America and Africa. Generally within the petrochemical and civil engineering industries.
I know dozens upon dozens of Rumanian and Bulgarian workers within the hospitality (Hotel & Apartment) business in the Eastern Med sunshine, each and every one is exceptionally hard working and I should add in my humble opinion being exploited by their employer - but that is only from my perspective. They seem to be happy with the situation, as they see it as a means to an end. I know one young lady working around 16 hours per day at everyones beck & call and who still finds time to study in what precious little spare time she has left. Yes they are paid far less than local labour, yes they are resented for having the job by locals but lets not blame them it is the system that permits it.
I would suggest that the real fear is not an influx of well educated, qualified and hard working individuals of which there are many but the remnants including a large proportion of Roma who perhaps see the UK as a vehicle to secure wealth which they may never otherwise have access to, part of which is of course the benefits system. Romania, Bulgaria and Hungary are very poor Countries in comparison to ours but lets never forget that we do exactly the same when we work in Hong Kong, Singapore, Kuala Lumpar, Brunei, Saudi, Kuwait, Russia, Norway, Sweden, Venezuela, Colombia, Libya, Bahrain, Phillipines etc. Homophobia has no place in civilised society but that is not to say governments should be blind to the realities and fears experienced by their citizens and in turn take whatever legal means there are to protect them. We have joined an EU club, we have reaped the benefit of membership, such as it is, we must now have to live by its rules of membership or lobby to change them.
