Immigration

I have to ask why we can't operate a immigration policy like Australia?, would it be so difficult, entry to the UK would be by a sponsor in the UK who provides a job and accommodation, yes we should have some people coming to this country but only the ones that benefit the UK, is it right that a Romanian family of 17 should be allowed to demand bigger accommodation for them, the benefit that they are claiming is they say £56K per year, this can't be right surely the EU can't say this is an acceptable situation for this country!!!!, what will happen when other countries join the EU up to 88 million people will be able to come to the UK, I am sorry to say that reality says we would just not be able to cope with any further influx of migrants, if the vote is stay God help us all especially our children because they will have to deal with it!!!.
