Isn't a little self defeating Gavin to be absolute that those in power are getting it all wrong when you have no alternative to propose that they should be doing instead?
I agree that complex matters rarely have soundbite solutions - if they did then previous governments would have had more success and the current one would be enjoying exceptional outcomes.
Jono appears to have a clear idea of an alternative approach to this issue. I'm inclined to agree that the matter is one of economics and how the economy is managed. Therefore I also agree that the government's blunt tools are not the answer, as is being proven through increasing footfalls.
An alternative then would be to exercise a fairer economic system, and one that contains a natural bias to the benefit of citizens, making citizenship the gateway to advantage, not residence. This does not prevent residents from gaining, nor preclude them from gaining citizenship, but it does put matters into a correct perspective without any racial division.
An interesting side effect of such an approach would be an ultimate deterrent of removal of citizenship for those guilty of, for instance extreme activities against the national interest, such as fraud or terrorism.
Introducing a new economic settlement is surely the best way to ensure that those gaining the most from their own activities are those persons themselves. Those who do little, or less, will reap the rewards in proportion with their own toil and achievement.
