Yes, simple isn't it.
A homeless person in the UK dies, on average aged 44.
Obviously they are doing it by choice, all they have to do is get a job to add on average 36 more years to their life. Simple.
And of course, homeless people are all layabouts, drug addicts, bums aren't they.
None of them are homeless because of the lack of affordable housing, or being evicted by a private landlord who decides to sell on a property with little to no notice, being ousted by parents who don't agree with their sexuality, or trying to escape an abusing partner.
Substance misuse is an issue that can obviously be resolved by just stopping right? It's absolutely nothing to do with the government provided facilities being woefully inadequate - and by that, I mean the attitudes towards mental health leading to the substance misuse, the difficulties in getting employment once branded as a junkie.
I suggest you stop calling them layabouts, dossers, bums, and start calling them people. Perhaps then you'd have some empathy. It's what separates us humans from the animals after all.
