That's the way they're used to living, OP -- they don't know any different, and if you gave them the chance at a "better life," they'd fuck it up until it's exactly like the one they have now.
One of my neighbors (a registered child sex offender who abused a 9-year-old girl and who lives two blocks away with his wife and three boys) has his yard almost entirely blocked from public view. There is only one way to see into it. I have to walk that way almost every day, so sadly, I see it. He has turned his big backyard into a trash dump, piles and piles of old chairs, mattresses, tires, trash bags, etc. And lots of dogs -- literally, junkyard dogs. He likes to set the trash on fire, blowing toxic fumes all over the neighborhood. Of course, three miles away is the local dump where it is completely free and legal to dump your trash, but why would one sully the back of one's gigantic truck by putting trash in it and driving it there? It's more fun to burn stuff.
When you guys write about people in poverty, it's so obvious to me that you have never lived in a dirt-poor neighborhood full of "good ol' boys." These are the kind of people that, if they won 20 million today in the lottery, they'd be living back in their old trailer in a year. They don't know how to make good decisions (financial or otherwise) or take care of nice things. Trump's gold toilet is their idea of what a rich person should spend his/her money on. They buy a new used vehicle and wreck it driving drunk a week later and lose their license because it's their third DUI. Still, they keep driving. And every single one of the things I write about here on DL is someone I know in my neighborhood. And yes, I'm a liberal Democrat, but one doesn't throw good money after bad.
I was walking up the street this morning at 7AM and saw a car careen around a corner and almost hit a pedestrian. A police car came up perhaps a minute later and turned lights and siren on. At 7 on a Sunday morning!
I worked as a statistician in a county child welfare agency (not in my current county) and when I researched "the literature" on social programs for children, statistically speaking, if you don't get them in those programs before they're 7, nothing will change their future behavior. That county still tried, though.
I keep telling you guys, no amount of money or social programs will help these people. They believe in their hearts there is absolutely nothing wrong with they way they live. You'd have to take the kids from them when they're born and have middle-class families raise them. And even then, heredity may still prevail.
Come visit me in Deplorable Haven! I'll give you the tour.
