But that ability isn't just down to luck! It's often down to people making difficult choices and sacrificing certain things in life to avoid spiralling into debt.
It'd be ridiculous to suggest that making responsible financial choices isn't a good thing. I agree that when you have choices - even if they're difficult, it's worth making them if it means avoiding debt and the interest, and stress, that accompanies it.
But not everyone has an actual choice, difficult or not. Sometimes there is literally just one thing you can do .... in order to keep your job, or to flee from an abusive relationship, or to feed your kids.
We all make financial choices - when we can based on various criteria such as our past experience of a given situation, our own research, our family responsibilities, professional advice and so on. I appreciate there'll always be a reckless minority who don't think things through but not everyone falls into that category. For those of us who've made 'sensible' choices and sacrifices, and have benefited from doing so, then we've been lucky not to have been adversely affected by things we couldn't have predicted. No-one has a crystal ball and even with the most cautious, well thought out approach to money, people are knocked sideways by unexpected illness, accident, the collapse of their employer, the birth of a child with disabilities, redundancy, relationships which gradually become abusive and so on.
So yes, it's disingenuous to dismiss 'luck' in all of this. People's lives are different. What can be shouldered and managed in one household won't necessarily be manageable in another regardless of how responsible they've been with their finances.
