It's the scandal of our times.
One of them, yes, but the thread is about homeless and lack of spaces to put them.
Supply and demand.
Market force, even at high property valuations, isn't providing supply of new builds because it doesn't pay well enough, so councils/taxes would have to pay for them.
Demand - well we do have an obvious source for that. Yes folk from war-torn countries want to emigrate and all countrries recognise an obligation to take some. But not all. The numbers have to be regulated.
Since pre brexit, the UK was one of the more welcoming countries to immigrants with regards to housing (EU report), with higher status given to them in housing applications than most other EU countries, which downgrade them.
Germany of course has the highest number of immigrants, but a report in July this year says that 25% of their 2015-16 influx is still in refugee shelters. This is despite councils paying landlords for the first 2 years rent for immigrants. Many areas in Germany have been saying "full". The Uk is attractive to migrants because of our policies. This i borne out by the numbers - roughly on a par with say Spain, despite the obviously different geographical situatons. It's for many reasons, one of which is lenience
International agreements will be just about impossible.
Sure, the trolls can use the matter as a stick to mindlessly hit our government of the day as their trope compels them, but that recourse is as squalid and wretched as the troll.
Part of the problem comes from a traditional Brit desire to be important in areas of strife, while not considering the comeback - the pun fits.
We don't have a legal framework to deter, unlike as that report said, most EU countries. There are things which can be done.
The example I referred to earlier illustrates. A man got here as a refugee. Therefore he could immediately bring his family. He got the odd job but couldn't support his family. He lost his job, the family split. The family weren't refugees but they weren't sent back, so became five more to be housed, educated and the rest. I think that attitude has to change, too.
