I'm from Ireland and it's similar here.
Our governments like to say the recession is over and we are climbing out and doing well. However, homelessness and the housing crisis is a lasting effect from the recession.
When the recession came about all them years ago, reading on online forums, there was so much blame being put onto peoples backs saying that we all partied with cheap credit from the banks and we weren't paying enough taxes. This blame was only for Ireland.
I always thought if that was the case, why is the UK suffering in a similar manner to us? The UK had a broadened tax base and lower social welfare to encourage work etc but they are suffering a recession too.
The USA also suffered a recession.
I always thought that the recession was far too deep for homegrown stuff to be reasons. There was no fix to the recession except for chasing after people and society for higher taxes and decreasing spending and services.
Anyways back to the homelessness.
The Crux of the problem, the job market for so many young adults was poor. Come on like, internships in poundland made the news. How was that right?
In my parents day, it took one person working and earning a wage to maintain a mortgage, a home, a family. Nowadays, a couple would struggle with two incomes (I suppose it depends on where and what they do).
There's definitely something not right and it goes very, very deep.
