I agree with user1471447863.
I know it's a touchy subject and there are those who are in genuinely difficult situations beyond their control, but for many it's down to poor choices, poor impulse control, and misplaced priorities.
My parents raised three children on a single income. It wasn't a high income, either. They budgeted carefully and made saving a priority. They still live that way. Though now the strict budgeting isn't necessary, frugality is just a way of life. Their version of a splurge wouldn't even register as a treat for many. Never owned a new car, always made do, bought second-hand, repaired, did as much as possible on their own, etc.
Compared to them, I'm probably a bit more of a "splurger", in some ways, but their example has left a strong impression that will always affect how I view money, spending, and savings. I can only imagine that the same is true for people who grew up witnessing a different way of dealing with money. It can be a challenge to break whatever cycle you're born into, and if you fall into bad luck, all the good habits in the world might not be enough to keep you afloat.
