It's just sweeping a problem under a carpet approach.
Real solution is alas one that eludes us today. The real issue is the blur in lines between economic migrant and refugee, with one used to bismish the other and anything to address the former being classed as an attack upon the later. Hence the whole subject is just a can or worms that just does not get dealt with.
As for the UK, when the majority of the economic and refugee's arrive via safe countries like France then it kinda adds a whole layer of debate that you just don't get with other countries migrant/refugee problems.
Honestly should be that people who need to escape a country for fear of their life should be able to walk into any other countries embasy and apply for asylum. That though is still not a thing, which only helps fuel illegal smugglers who will take refugees and economic migrants equally if they have the money. Which is the bigger sadness of all with how things are working currently as how many true refugee's in fear of their life have died as they had no means to pay for a way out! That whole aspect of thought is just sadening and yet, overlooked as the focus is all about those who had the means or morals to pay smugglers and can imagine there are those who probably had the means but equally ethics and morals that meant they were unwilling to pay in effect crimininals.
So I guess changing how people apply for Ayslum and the ability to walk into the nearest forign embassy would certainly be a start in solving things.
Then distibution equally needs to be fair around the Globe, so no one country becomes burgened, though that would be a whole area of debate the UN could work out. Certainly the ability to apply at embassys would be huge improvment.
