The issue here isn't a simple choice. Can you imagine having nothing in this world? Truly not knowing where your next is coming? Not being able to use a bathroom when you need to? To have had all life's accoutrements stripped away - photographs, furniture, jewelry, clothes, etc. What do these people have? In their case, they have each other. In consecutive days of doubt, fear, and worry - they at least have their partner beside them.
Saying goodbye, in those circumstances, would be extremely difficult and just add another worry (what is my wife going through). With poverty, your world gets very small. You might go from traveling the country, or even the world, to being confined in a filthy street with no amenities. Danger is all around, from addicts to criminal gangs. It's not always so easy. When you're on the bottom, and then find another distance to fall... just horrible.
I can't say what instigated that jibe, but my assumption was that it was a reference to the "Who is worse, Cat or Dog Owners" thread that happened recently.
For the record, I have a dog, and I'm thinking of getting another. The dog is 100% reliant on me. In some ways he's a dumb animal, a living, breathing, creature who offers a distraction from a world full of angst and disasters. A dog, generally, has the ability to learn 165 words. So let's say, conversations are limited, and are mostly one way. But I love this piece of nature I have welcomed into my home. I have made a commitment to care for him, and I hold to that responsibility. Pets matter.
Back to homelessness - it's not simply a matter of getting people off the street. I hear myself saying this over and over - but being on the street is a symptom of something. You have to get to the cause. Plenty of money has been spent on the problem, but that money has to be spent intelligently, and that's not always the case.
In the UK, and no doubt elsewhere, we have many issues. One issue are single parents. In the UK currently, there are 120,000 families in temporary accommodation (which for us is emergency housing that might be in hotels etc.) That's adults. They come with 150,000 children. If that doesn't point to an area of societal breakdown, I don't know what does. Fathers failing to take responsibility for their children, women having children when they should know better, domestic violence, drug addiction, the reasons seem endless. We'll have long-term bad consequences for allowing children to suffer through this.
