Firstly, the EU doesn't have spare islands to dump hundreds of thousands - millions of refugees onto. Secondly, there won't be better living conditions than the Australian model, because at every step governments will penny-pinch, not least from huge pressure from those same people who want all illegal immigrants blocked, because they are outraged at the idea their countries spend any money at all on them. (The same people overwhelmingly oppose foreign aid, etc.) Thirdly, we don't know what countries a lot of them come from to return them to, because they don't have (will even have deliberately thrown away) their ID, and other countries don't want to take back people who could as easily be random anybodies. Fourthly, damaging the economies of developing world countries by banning financial transactions with them is going to enhance social breakdown in those countries... which will generate a refugee crisis. Never mind the hardship this might inflict on the innocent.Nope, I mean the Australian model (with better living conditions in the detention centers) combined with political pressure to force said countries to accept their citizens back. A country should never be able to refuse one of its citizens, now THAT is inhumane. But we all know why that is, they're lowly skilled and once in the EU they will either have a min. wage job or benefit from welfare and transfer a part of it to family in the home country. Well, block financial transfers to that country if it blocks re-entry for its own citizens.
There is a certain point where our governments cannot take responsibility for what goes on outside their borders. If people want to pay criminal gangs thousands of Euros and risk their lives to get to the EU, that's their choice in jurisdictions outside the EU's remit. The EU's remit for the most part starts at the Mediterranean. It can after that attempt to mitigate refugees by helping prevent the causes of refugees, or agreeing deals various deals with other countries.So instead we have a shitty immoral system which encourages people taking deadly risks.
The main causes of refugees are civil disorder, warfare, and economic collapse. They feel their lives are utterly hopeless if they stay, so they leave. And when they leave, some of them will come to the EU under any circumstance whatsoever. They already know the exploitation, risk of failure and risk of death, and yet they still come. That's how desperate and determined they are. Unless the EU enacts policies to reduce their hopes below that of the misery they already have - which are policies of terrifying inhumanity - they will continue to come. It is essential to grasp this fact: people who feel they have nothing will do almost anything for a chance of having something.
