At least in Australia they make a fair go of actually running a system which by and large tries to take skilled immigrants and has an organised system for distributing them to areas where skills are in demand etc.
Unfortunately for the UK, it has taken in several million largely unskilled third world migrants in the last 15 years, and are about to open the door to potentially hundreds of thousands more when Romanians and Bulgarians are permitted access in the New Year.
The UK has, and continues to importing the bottom of the barrel from countries around the world, and losing many of it's skilled residents to countries which now offer a better quality of life and more prospects and which actually have proper immigration policies that attract skilled people who can add value in a real knowledge economy - not those who come to sell pound a bowl fruit for cash down the market, claim benefits, or send money from earnings back "home", leaving the UK economy entirely.
What the UK has done to itself is not normal, it's borne of total incompetence by those who govern and administrate.
Do the Brits want even more police resources tied up in tracking down overseas crime networks who come and go and operate in the UK as they please?
Some people who write here believe their own hype of the joys of unskilled mass immigration. Britain is not looked at as a "beacon of tolerance and multicultural peace" - it's well regarded to have in the last 15 years utterly failed in controlling it's borders, whilst allowing unfettered acesss to people from every corner of the world, regardless of ability, or worth, or honesty, or desire to to fit in.
Looking from the outside, other European countries are only too happy to funnel these people to the UK - they know the authorities are incompetent and often compliant.
Things have got to such a stage now that are now thousands upon thousands of illegal overcrowded shanties / sheds which people live in, being built in East London boroughs and other places, by migrants, legal and illegal, every single day due to this uncontrolled influx. Living conditions that have not existed for over 100 years.
All very well to look the other way and stick your fingers in your ears and say "we're all immigrants really" and pretend it's all great but reality will catch up.
There's big trouble ahead for the UK - it's a powder keg, and i can well see why many people are now getting to the point where they feel strangers in their own country.
